Quasar is a popular Vue UI library for developing good looking Vue apps.
In this article, we’ll take a look at how to create Vue apps with the Quasar UI library.
Option Groups
We can add option groups into our Vue app with Quasar’sq-option-group component.
For instance, we can write:
<!DOCTYPE html>
<html>
<head>
<link
href="https://fonts.googleapis.com/css?family=Roboto:100,300,400,500,700,900|Material+Icons"
rel="stylesheet"
type="text/css"
/>
<link
href="https://cdn.jsdelivr.net/npm/quasar@1.12.13/dist/quasar.min.css"
rel="stylesheet"
type="text/css"
/>
</head>
<body class="body--dark">
<script src="https://cdn.jsdelivr.net/npm/vue@^2.0.0/dist/vue.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/quasar@1.12.13/dist/quasar.umd.min.js"></script>
<div id="q-app">
<q-layout
view="lHh Lpr lFf"
container
style="height: 100vh;"
class="shadow-2 rounded-borders"
>
<div class="q-pa-md">
<q-option-group v-model="group" :options="options" color="primary">
</q-option-group>
</div>
</q-layout>
</div>
<script>
new Vue({
el: "#q-app",
data: {
group: "op1",
options: [
{
label: "Option 1",
value: "op1"
},
{
label: "Option 2",
value: "op2"
},
{
label: "Option 3",
value: "op3"
}
]
}
});
</script>
</body>
</html>
We set the options prop to set the options.
A group of radio buttons will be rendered.
We can set the type prop to checkbox to show a group of checkboxes:
<!DOCTYPE html>
<html>
<head>
<link
href="https://fonts.googleapis.com/css?family=Roboto:100,300,400,500,700,900|Material+Icons"
rel="stylesheet"
type="text/css"
/>
<link
href="https://cdn.jsdelivr.net/npm/quasar@1.12.13/dist/quasar.min.css"
rel="stylesheet"
type="text/css"
/>
</head>
<body class="body--dark">
<script src="https://cdn.jsdelivr.net/npm/vue@^2.0.0/dist/vue.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/quasar@1.12.13/dist/quasar.umd.min.js"></script>
<div id="q-app">
<q-layout
view="lHh Lpr lFf"
container
style="height: 100vh;"
class="shadow-2 rounded-borders"
>
<div class="q-pa-md">
<q-option-group
v-model="group"
type="checkbox"
:options="options"
color="primary"
>
</q-option-group>
</div>
</q-layout>
</div>
<script>
new Vue({
el: "#q-app",
data: {
group: ["op1"],
options: [
{
label: "Option 1",
value: "op1"
},
{
label: "Option 2",
value: "op2"
},
{
label: "Option 3",
value: "op3"
}
]
}
});
</script>
</body>
</html>
We set the group model value to an array since we can select multiple values.
Also, we can set the type to toggle to let us render a group of toggle switches:
<!DOCTYPE html>
<html>
<head>
<link
href="https://fonts.googleapis.com/css?family=Roboto:100,300,400,500,700,900|Material+Icons"
rel="stylesheet"
type="text/css"
/>
<link
href="https://cdn.jsdelivr.net/npm/quasar@1.12.13/dist/quasar.min.css"
rel="stylesheet"
type="text/css"
/>
</head>
<body class="body--dark">
<script src="https://cdn.jsdelivr.net/npm/vue@^2.0.0/dist/vue.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/quasar@1.12.13/dist/quasar.umd.min.js"></script>
<div id="q-app">
<q-layout
view="lHh Lpr lFf"
container
style="height: 100vh;"
class="shadow-2 rounded-borders"
>
<div class="q-pa-md">
<q-option-group
v-model="group"
type="toggle"
:options="options"
color="primary"
>
</q-option-group>
</div>
</q-layout>
</div>
<script>
new Vue({
el: "#q-app",
data: {
group: ["op1"],
options: [
{
label: "Option 1",
value: "op1"
},
{
label: "Option 2",
value: "op2"
},
{
label: "Option 3",
value: "op3"
}
]
}
});
</script>
</body>
</html>
We can put the labels on the left side with the left-label prop:
<!DOCTYPE html>
<html>
<head>
<link
href="https://fonts.googleapis.com/css?family=Roboto:100,300,400,500,700,900|Material+Icons"
rel="stylesheet"
type="text/css"
/>
<link
href="https://cdn.jsdelivr.net/npm/quasar@1.12.13/dist/quasar.min.css"
rel="stylesheet"
type="text/css"
/>
</head>
<body class="body--dark">
<script src="https://cdn.jsdelivr.net/npm/vue@^2.0.0/dist/vue.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/quasar@1.12.13/dist/quasar.umd.min.js"></script>
<div id="q-app">
<q-layout
view="lHh Lpr lFf"
container
style="height: 100vh;"
class="shadow-2 rounded-borders"
>
<div class="q-pa-md">
<q-option-group
v-model="group"
left-label
:options="options"
color="primary"
>
</q-option-group>
</div>
</q-layout>
</div>
<script>
new Vue({
el: "#q-app",
data: {
group: "op1",
options: [
{
label: "Option 1",
value: "op1"
},
{
label: "Option 2",
value: "op2"
},
{
label: "Option 3",
value: "op3"
}
]
}
});
</script>
</body>
</html>
Conclusion
We can use Quasar’s q-option-group component to render a group of checkboxes, radio buttons, or toggles.
