Vuetify is a popular UI framework for Vue apps.

In this article, we’ll look at how to work with the Vuetify framework.

Data Tables Search

We can add a search prop to allow us to filter data in a data table.

For example, we can write:

<template>
  <v-card>
    <v-card-title>
      Nutrition
      <v-spacer></v-spacer>
      <v-text-field
        v-model="search"
        append-icon="mdi-magnify"
        label="Search"
        single-line
        hide-details
      ></v-text-field>
    </v-card-title>
    <v-data-table :headers="headers" :items="desserts" :search="search"></v-data-table>
  </v-card>
</template>
<script>
export default {
  name: "HelloWorld",
  data: () => ({
    search: "",
    headers: [
      {
        text: "Dessert (100g serving)",
        align: "start",
        sortable: false,
        value: "name",
      },
      { text: "Calories", value: "calories" },
      { text: "Fat (g)", value: "fat" },
    ],
    desserts: [
      {
        name: "Frozen Yogurt",
        calories: 200,
        fat: 6.0,
      },
      {
        name: "Ice cream sandwich",
        calories: 200,
        fat: 9.0,
      },
      {
        name: "Eclair",
        calories: 300,
        fat: 16.0,
      },
    ],
  }),
};
</script>

We add the v-text-field that binds to the search state.

We pass search into the search prop and we can search any column we like.

Remove Default Header and Footer

The hide-default-header and hide-default-footer props let us remove the default header and footer.

For example, we can write:

<template>
  <v-data-table
    :headers="headers"
    :items="desserts"
    hide-default-header
    hide-default-footer
    class="elevation-1"
  ></v-data-table>
</template>
<script>
export default {
  name: "HelloWorld",
  data: () => ({
    search: "",
    headers: [
      {
        text: "Dessert (100g serving)",
        align: "start",
        sortable: false,
        value: "name",
      },
      { text: "Calories", value: "calories" },
      { text: "Fat (g)", value: "fat" },
    ],
    desserts: [
      {
        name: "Frozen Yogurt",
        calories: 200,
        fat: 6.0,
      },
      {
        name: "Ice cream sandwich",
        calories: 200,
        fat: 9.0,
      },
      {
        name: "Eclair",
        calories: 300,
        fat: 16.0,
      },
    ],
  }),
};
</script>

Loading State

We can add the loading prop to indicate that the table is loading.

Also, we can display a message when the table is loading.

For example, we can write:

<template>
  <v-data-table item-key="name" class="elevation-1" loading loading-text="Loading... Please wait"></v-data-table>
</template>
<script>
export default {
  name: "HelloWorld",
  data: () => ({}),
};
</script>

The loading-text lets us set the loading text to display.

Dense

We can add the dense prop to make the rows shorter:

<template>
  <v-data-table :headers="headers" :items="desserts" dense class="elevation-1"></v-data-table>
</template>
<script>
export default {
  name: "HelloWorld",
  data: () => ({
    search: "",
    headers: [
      {
        text: "Dessert (100g serving)",
        align: "start",
        sortable: false,
        value: "name",
      },
      { text: "Calories", value: "calories" },
      { text: "Fat (g)", value: "fat" },
    ],
    desserts: [
      {
        name: "Frozen Yogurt",
        calories: 200,
        fat: 6.0,
      },
      {
        name: "Ice cream sandwich",
        calories: 200,
        fat: 9.0,
      },
      {
        name: "Eclair",
        calories: 300,
        fat: 16.0,
      },
    ],
  }),
};
</script>

Now the rows are shorter.

Conclusion

We can customize our table with search, sorting, and pagination with Vuetify.

Data Tables

The v-data-table component is used to display tabular data.

It includes features like sorting, searching, pagination, editing, and row selection.

For example, we can write:

<template>
  <v-data-table
    v-model="selected"
    :headers="headers"
    :items="desserts"
    :single-select="singleSelect"
    item-key="name"
    show-select
    class="elevation-1"
  >
    <template v-slot:top>
      <v-subheader>Dessert</v-subheader>
    </template>
  </v-data-table>
</template>
<script>
export default {
  name: "HelloWorld",
  data: () => ({
    singleSelect: false,
    selected: [],
    headers: [
      {
        text: "Dessert (100g serving)",
        align: "start",
        sortable: false,
        value: "name",
      },
      { text: "Calories", value: "calories" },
      { text: "Fat (g)", value: "fat" },
    ],
    desserts: [
      {
        name: "Frozen Yogurt",
        calories: 159,
        fat: 6.0,
      },
      {
        name: "Ice cream sandwich",
        calories: 237,
        fat: 9.0,
      },
      {
        name: "Eclair",
        calories: 262,
        fat: 16.0,
      },
    ],
  }),
};
</script>

We have the v-data-table component to add our table.

The v-model has the selected rows.

items have the items to display.

single-select lets us toggle single select.

The headers prop have the headers.

The value is an array with some objects.

The text property has the column heading text.

align has the text alignment.

sortable lets us set whether it’s sortable or not.

value has the property name of the entry to display.

Pagination is automatically included.

Grouped Rows

We can group different rows together with the group-by and group-desc props.

For example, we can write:

<template>
  <v-data-table
    v-model="selected"
    :headers="headers"
    :items="desserts"
    :single-select="singleSelect"
    item-key="name"
    show-group-by
    group-by="category"
    class="elevation-1"
  >
    <template v-slot:top>
      <v-subheader>Dessert</v-subheader>
    </template>
  </v-data-table>
</template>
<script>
export default {
  name: "HelloWorld",
  data: () => ({
    headers: [
      {
        text: "Dessert (100g serving)",
        align: "start",
        value: "name",
        groupable: false,
      },
      { text: "Category", value: "category", align: "right" },
      { text: "Dairy", value: "dairy", align: "right" },
    ],
    desserts: [
      {
        name: "Frozen Yogurt",
        category: "Ice cream",
        dairy: "Yes",
      },
      {
        name: "Ice cream sandwich",
        category: "Ice cream",
        dairy: "Yes",
      },
      {
        name: "Eclair",
        category: "Cookie",
        dairy: "Yes",
      },
    ],
  }),
};
</script>

We have the v-data-table component to display items in a group.

The group-by prop takes the string with the property key to group by.

The show-group-by prop lets us add the group by button to let us group by the properties.

Sort on Multiple Columns

We can sort a table by multiple columns.

For example, we can write:

<template>
  <v-data-table
    :headers="headers"
    :items="desserts"
    :sort-by="['calories', 'fat']"
    :sort-desc="[false, true]"
    multi-sort
    class="elevation-1"
  ></v-data-table>
</template>
<script>
export default {
  name: "HelloWorld",
  data: () => ({
    headers: [
      {
        text: "Dessert (100g serving)",
        align: "start",
        sortable: false,
        value: "name",
      },
      { text: "Calories", value: "calories" },
      { text: "Fat (g)", value: "fat" },
    ],
    desserts: [
      {
        name: "Frozen Yogurt",
        calories: 200,
        fat: 6.0,
      },
      {
        name: "Ice cream sandwich",
        calories: 200,
        fat: 9.0,
      },
      {
        name: "Eclair",
        calories: 300,
        fat: 16.0,
      },
    ],
  }),
};
</script>

We added the sort-by prop with an array of the property names to sort by.

sort-desc lets us set whether to sort the column in the position in sort-by in descending order or not.

Conclusion

We can add tables that can be sorted and grouped with Vuetify.

Data Iterator — Expanding Items

We can expand and collapse items with the v-data-iterator component.

For example, we can write:

<template>
  <v-container fluid>
    <v-data-iterator
      :items="items"
      item-key="name"
      :items-per-page="4"
      :single-expand="expand"
      hide-default-footer
    >
      <template v-slot:default="{ items, isExpanded, expand }">
        <v-row>
          <v-col v-for="item in items" :key="item.name" cols="12" sm="6" md="4" lg="3">
            <v-card>
              <v-card-title>
                <h4>{{ item.name }}</h4>
              </v-card-title>
              <v-switch
                :input-value="isExpanded(item)"
                :label="isExpanded(item) ? 'Expanded' : 'Closed'"
                class="pl-4 mt-0"
                @change="(v) => expand(item, v)"
              ></v-switch>
              <v-divider></v-divider>
              <v-list v-if="isExpanded(item)" dense>
                <v-list-item>
                  <v-list-item-content>Calories:</v-list-item-content>
                  <v-list-item-content class="align-end">{{ item.calories }}</v-list-item-content>
                </v-list-item>
                <v-list-item>
                  <v-list-item-content>Fat:</v-list-item-content>
                  <v-list-item-content class="align-end">{{ item.fat }}</v-list-item-content>
                </v-list-item>
              </v-list>
            </v-card>
          </v-col>
        </v-row>
      </template>
    </v-data-iterator>
  </v-container>
</template>
<script>
export default {
  name: "HelloWorld",
  data: () => ({
    itemsPerPage: 4,
    items: [
      {
        name: "Yogurt",
        calories: 159,
        fat: 6.0,
      },
      {
        name: "Ice cream sandwich",
        calories: 237,
        fat: 9.0,
      },
      {
        name: "Donuts",
        calories: 262,
        fat: 16.0,
      },
      {
        name: "Cupcake",
        calories: 305,
        fat: 3.7,
      },
    ],
  }),
};
</script>

We get the isExpanded function from the default slot to style our entries differently if it’s expanded or not.

The expand function from the slot lets us expand or collapse the entry if we click on the v-switch .

Filter Items

We can order, filter, and paginate items.

For example, we can write:

<template>
  <v-container fluid>
    <v-data-iterator
      :items="items"
      :items-per-page.sync="itemsPerPage"
      :page="page"
      :search="search"
      :sort-by="sortBy.toLowerCase()"
      :sort-desc="sortDesc"
      hide-default-footer
    >
      <template v-slot:header>
        <v-toolbar dark color="blue darken-3" class="mb-1">
          <v-text-field
            v-model="search"
            clearable
            flat
            solo-inverted
            hide-details
            prepend-inner-icon="search"
            label="Search"
          ></v-text-field>
          <template v-if="$vuetify.breakpoint.mdAndUp">
            <v-spacer></v-spacer>
            <v-select
              v-model="sortBy"
              flat
              solo-inverted
              hide-details
              :items="keys"
              prepend-inner-icon="search"
              label="Sort by"
            ></v-select>
            <v-spacer></v-spacer>
            <v-btn-toggle v-model="sortDesc" mandatory>
              <v-btn large depressed color="blue" :value="false">
                <v-icon>mdi-arrow-up</v-icon>
              </v-btn>
              <v-btn large depressed color="blue" :value="true">
                <v-icon>mdi-arrow-down</v-icon>
              </v-btn>
            </v-btn-toggle>
          </template>
        </v-toolbar>
      </template>

      <template v-slot:default="props">
        <v-row>
          <v-col v-for="item in props.items" :key="item.name" cols="12" sm="6" md="4" lg="3">
            <v-card>
              <v-card-title class="subheading font-weight-bold">{{ item.name }}</v-card-title>

              <v-divider></v-divider>

              <v-list dense>
                <v-list-item v-for="(key, index) in filteredKeys" :key="index">
                  <v-list-item-content :class="{ 'blue--text': sortBy === key }">{{ key }}:</v-list-item-content>
                  <v-list-item-content
                    class="align-end"
                    :class="{ 'blue--text': sortBy === key }"
                  >{{ item[key.toLowerCase()] }}</v-list-item-content>
                </v-list-item>
              </v-list>
            </v-card>
          </v-col>
        </v-row>
      </template>

      <template v-slot:footer>
        <v-row class="mt-2" align="center" justify="center">
          <span class="grey--text">Items per page</span>
          <v-menu offset-y>
            <template v-slot:activator="{ on, attrs }">
              <v-btn dark text color="primary" class="ml-2" v-bind="attrs" v-on="on">
                {{ itemsPerPage }}
                <v-icon>mdi-chevron-down</v-icon>
              </v-btn>
            </template>
            <v-list>
              <v-list-item
                v-for="(number, index) in itemsPerPageArray"
                :key="index"
                @click="updateItemsPerPage(number)"
              >
                <v-list-item-title>{{ number }}</v-list-item-title>
              </v-list-item>
            </v-list>
          </v-menu>

          <v-spacer></v-spacer>

          <span class="mr-4 grey--text">Page {{ page }} of {{ numberOfPages }}</span>
          <v-btn fab dark color="blue darken-3" class="mr-1" @click="formerPage">
            <v-icon>mdi-chevron-left</v-icon>
          </v-btn>
          <v-btn fab dark color="blue darken-3" class="ml-1" @click="nextPage">
            <v-icon>mdi-chevron-right</v-icon>
          </v-btn>
        </v-row>
      </template>
    </v-data-iterator>
  </v-container>
</template>
<script>
export default {
  name: "HelloWorld",
  data: () => ({
    itemsPerPageArray: [1, 2],
    search: "",
    filter: {},
    sortDesc: false,
    page: 1,
    itemsPerPage: 1,
    sortBy: "name",
    keys: ["Name", "Calories", "Fat"],
    items: [
      {
        name: "Yogurt",
        calories: 159,
        fat: 6.0,
      },
      {
        name: "Ice cream sandwich",
        calories: 237,
        fat: 9.0,
      },
      {
        name: "Donuts",
        calories: 262,
        fat: 16.0,
      },
      {
        name: "Cupcake",
        calories: 305,
        fat: 3.7,
      },
    ],
  }),
  computed: {
    numberOfPages() {
      return Math.ceil(this.items.length / this.itemsPerPage);
    },
    filteredKeys() {
      return this.keys.filter((key) => key !== `Name`);
    },
  },
  methods: {
    nextPage() {
      if (this.page + 1 <= this.numberOfPages) this.page += 1;
    },
    formerPage() {
      if (this.page - 1 >= 1) this.page -= 1;
    },
    updateItemsPerPage(number) {
      this.itemsPerPage = number;
    },
  },
};
</script>

We have the text field to search for items in the header slot.

The search state will be set if we type something into the text field in the header.

The v-btn-toggle component lets us toggle the sorting between forward and reverse order.

When we click on the buttons, we toggle the sortDesc state.

Also, we have a dropdown that sets the sortBy state to let us sort items by the given key automatically.

All the states are used as prop values in the v-data-iterator component.

Then all the sorting, pagination, and search logic will be taken care of by the v-data-iterator .

We also have a v-select to let us change the number of items per page with the updateItemsPerPage method.

The content is populated in the default slot.

The props.items property has the items that we want to render into cards.

Conclusion

We can add sorting, pagination, and searching with the v-data-iterator component with a few props.

Time Picker Width

We can set the width of a time picker with the width prop:

<template>  
  <v-row justify="space-around">  
    <v-time-picker v-model="time" type="month" width="290" class="ml-4"></v-time-picker>  
  </v-row>  
</template>  
<script>  
export default {  
  name: "HelloWorld",  
  data: () => ({  
    time: "11:15",  
  }),  
};  
</script>

The width is in pixels.

Also, we can add the full-width prop to make the time picker full width:

<template>  
  <v-row justify="space-around">  
    <v-time-picker v-model="time" :landscape="$vuetify.breakpoint.mdAndUp" full-width type="month"></v-time-picker>  
  </v-row>  
</template>  
<script>  
export default {  
  name: "HelloWorld",  
  data: () => ({  
    time: "11:15",  
  }),  
};  
</script>

We can set it to landscape mode at the breakpoint we want so that the header will be displayed as the sidebar.

Time Picker’s Elevation

A time picker can have a shadow below it.

We can add the flat prop to remove the shadow:

<template>  
  <v-row justify="space-around">  
    <v-time-picker v-model="time" flat></v-time-picker>  
  </v-row>  
</template>  
<script>  
export default {  
  name: "HelloWorld",  
  data: () => ({  
    time: "11:15",  
  }),  
};  
</script>

Or we can add the elevation prop to add our shadow:

<template>  
  <v-row justify="space-around">  
    <v-time-picker v-model="time" elevation="15"></v-time-picker>  
  </v-row>  
</template>  
<script>  
export default {  
  name: "HelloWorld",  
  data: () => ({  
    time: "11:15",  
  }),  
};  
</script>

The value is between 0 to 24.

AM/PM Switch in Title

We can add the ampm-in-title prop to add the AM and PM text into the header.

For example, we can write:

<template>  
  <v-row justify="space-around">  
    <v-time-picker v-model="time" ampm-in-title></v-time-picker>  
  </v-row>  
</template>  
<script>  
export default {  
  name: "HelloWorld",  
  data: () => ({  
    time: "11:15",  
  }),  
};  
</script>

This way, we can choose an AM or PM time.

No Title

We can remove the title bar with the no-title prop:

<template>  
  <v-row justify="space-around">  
    <v-time-picker v-model="time" no-title></v-time-picker>  
  </v-row>  
</template>  
<script>  
export default {  
  name: "HelloWorld",  
  data: () => ({  
    time: "11:15",  
  }),  
};  
</script>

Time Picker With Seconds

A time picker can let us choose the seconds.

To do that, we add the use-seconds prop:

<template>  
  <v-row justify="space-around">  
    <v-time-picker v-model="picker" use-seconds></v-time-picker>  
  </v-row>  
</template>  
<script>  
export default {  
  name: "HelloWorld",  
  data: () => ({  
    time: "11:15",  
  }),  
};  
</script>

Now we can pick the seconds.

Scrollable Time Picker

We can make the time values scrollable with the scrollable prop:

<template>  
  <v-row justify="space-around">  
    <v-time-picker v-model="picker" scrollable></v-time-picker>  
  </v-row>  
</template>  
<script>  
export default {  
  name: "HelloWorld",  
  data: () => ({  
    time: "11:15",  
  }),  
};  
</script>

Now we pick our time values by scrolling with the scroll wheel.

Range

The time value range can be restricted with the min and max props:

<template>  
  <v-row justify="space-around" align="center">  
    <v-col style="width: 290px; flex: 0 1 auto;">  
      <h2>Start:</h2>  
      <v-time-picker v-model="start" :max="end"></v-time-picker>  
    </v-col>  
    <v-col style="width: 290px; flex: 0 1 auto;">  
      <h2>End:</h2>  
      <v-time-picker v-model="end" :min="start"></v-time-picker>  
    </v-col>  
  </v-row>  
</template>  
<script>  
export default {  
  name: "HelloWorld",  
  data: () => ({  
    start: null,  
    end: null,  
  }),  
};  
</script>

We have the max prop to set the maximum time we can choose.

And the min prop sets a minimum time restriction.

Conclusion

We can customize time pickers in many ways.

Vuetify is a popular UI framework for Vue apps.

In this article, we’ll look at how to work with the Vuetify framework.

Subheaders

The v-subheader component is used to separate sections of lists.

For example, we can write:

<template>
  <v-col cols="12" sm="6" offset-sm="3">
    <v-card>
      <v-subheader :inset="inset">Subheader</v-subheader>

      <v-list>
        <template v-for="(item, index) in items">
          <v-list-item v-if="item.action" :key="item.title">
            <v-list-item-action>
              <v-icon>{{ item.action }}</v-icon>
            </v-list-item-action>

            <v-list-item-content>
              <v-list-item-title>{{ item.title }}</v-list-item-title>
            </v-list-item-content>
          </v-list-item>

          <v-divider v-else-if="item.divider" :key="index" :inset="inset"></v-divider>
        </template>
      </v-list>
    </v-card>
  </v-col>
</template>
<script>
export default {
  name: "HelloWorld",
  data: () => ({
    inset: true,
    items: [
      {
        action: "label",
        title: "List item 1",
      },
      {
        divider: true,
      },
      {
        action: "label",
        title: "List item 2",
      },
      {
        divider: true,
      },
      {
        action: "label",
        title: "List item 3",
      },
    ],
  }),
};
</script>

We have the v-subheader component on top of a list.

It’ll be aligned to the text of the list with the inset prop.

Grid Subheaders

We can add subheaders above a grid.

For example, we can write:

<template>
  <v-row>
    <v-col cols="12" sm="6" offset-sm="3">
      <v-card>
        <v-subheader>May</v-subheader>
        <v-container fluid>
          <v-row>
            <v-col v-for="i in 6" :key="i" cols="4">
              <img
               :src="`https://randomuser.me/api/portraits/men/${i}.jpg`"
                class="image"
                height="100%"
                width="100%"
              />
            </v-col>
          </v-row>
        </v-container>
      </v-card>
    </v-col>
  </v-row>
</template>
<script>
export default {
  name: "HelloWorld",
  data: () => ({}),
};
</script>

We have the v-subheader on top of a grid.

Menu Subheaders

Subheaders also fit automatically in menus.

For example, we can write:

<template>
  <v-row>
    <v-col cols="12" sm="6" offset-sm="3">
      <v-card>
        <v-toolbar color="teal" dark>
          <v-app-bar-nav-icon></v-app-bar-nav-icon>

           <v-toolbar-title>Manage</v-toolbar-title>

          <v-spacer></v-spacer>

          <v-btn icon>
            <v-icon>mdi-dots-vertical</v-icon>
          </v-btn>
        </v-toolbar>

        <v-list>
          <template v-for="(item, index) in items">
            <v-list-item v-if="item.action" :key="item.title">
              <v-list-item-action>
                <v-icon>{{ item.action }}</v-icon>
              </v-list-item-action>

              <v-list-item-content>
                <v-list-item-title>{{ item.title }}</v-list-item-title>
              </v-list-item-content>
            </v-list-item>

            <v-divider v-else-if="item.divider" :key="index"></v-divider>

            <v-subheader v-else-if="item.header" :key="item.header">{{ item.header }}</v-subheader>
          </template>
        </v-list>
      </v-card>
    </v-col>
  </v-row>
</template>
<script>
export default {
  name: "HelloWorld",
  data: () => ({
    items: [
      {
        action: "move_to_inbox",
        title: "Inbox",
      },
      {
        action: "send",
        title: "Sent",
      },
      { divider: true },
      { header: "Labels" },
      {
        action: "label",
        title: "Family",
      },
    ],
  }),
};
</script>

We created a v-list with the items.

The v-subheader is one of the types of items that we’re looping through within the v-list component.

The subheader will be aligned with the menu text without any extra styles.

Conclusion

Subheaders are useful for titles for lists.
