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.
Toggles in Option Groups
We can add a group of toggles with the q-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
:options="options"
label="Notifications"
type="toggle"
v-model="group"
>
</q-option-group>
</div>
</q-layout>
</div>
<script>
new Vue({
el: "#q-app",
data: {
group: [],
options: [
{ label: "Battery low", value: "bat" },
{ label: "Friend request", value: "friend", color: "green" },
{ label: "Picture uploaded", value: "upload", color: "red" }
]
}
});
</script>
</body>
</html>
Button Toggle
Quasar comes with the q-btn-toggle component that renders a button toggle.
To use it, we 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-btn-toggle
v-model="model"
push
glossy
toggle-color="primary"
:options="options"
>
</q-btn-toggle>
</div>
</q-layout>
</div>
<script>
new Vue({
el: "#q-app",
data: {
model: "",
options: [
{ label: "Battery low", value: "bat" },
{ label: "Friend request", value: "friend", color: "green" },
{ label: "Picture uploaded", value: "upload", color: "red" }
]
}
});
</script>
</body>
</html>
We add the push prop to let users push the buttons.
glossy adds a glossy effect.
And the toggle-color prop sets the color of the toggled element.
options sets the options for the button toggle.
We can replace glossy with flat , rounded and unelevated to change the styles.
no-caps changes the button text to be sentence case.
We can spread the button toggle across the screen with the spread 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-btn-toggle
v-model="model"
spread
no-caps
toggle-color="purple"
color="white"
text-color="black"
toggle-color="primary"
:options="options"
>
</q-btn-toggle>
</div>
</q-layout>
</div>
<script>
new Vue({
el: "#q-app",
data: {
model: "",
options: [
{ label: "Battery low", value: "bat" },
{ label: "Friend request", value: "friend", color: "green" },
{ label: "Picture uploaded", value: "upload", color: "red" }
]
}
});
</script>
</body>
</html>
Conclusion
We can add a button toggle into our Vue app with Quasar’sq-btn-toggle component.
