Floating Action Buttons     

A Quasar Floating Action Button (FAB) represents the primary action in an App Page. But, it’s not limited to only a single action. It can contain any number of sub-actions too. And more importantly, it can also be used inline in your Pages or Layouts.

Note that you don’t need a QLayout to use FABs.

Basic Usage

There are two types of FABs: expandable (has sub-actions) and non-expandable.

Non-Expandable

If you want a non-expandable FAB, all you need is a round button – wrapped in QFixedPosition if used on a QLayout.

<!-- Non-expandable without being on a QLayout -->
<q-btn
round
color="primary"
@click="method"
class="fixed"
style="right: 18px; bottom: 18px"
>
<q-icon name="mail" />
</q-btn>

<!-- Non-expandable on a QLayout -->
<q-fixed-position corner="bottom-right" :offset="[18, 18]">
<q-btn round color="primary" @click="method">
<q-icon name="mail" />
</q-btn>
</q-fixed-position>

Expandable

Expandable FABs are defined by two components: QFab (parent) and QFabAction (children).

<!-- Expandable -->
<q-fab
color="purple"
icon="keyboard_arrow_up"
direction="up"
>
<q-fab-action
color="primary"
@click="someMethod"
icon="mail"
/>

<q-fab-action
color="secondary"
@click="someMethod"
icon="alarm"
/>
</q-fab>

<!-- Expandable, fixed position without a QLayout -->
<q-fab
class="fixed"
style="right: 18px; bottom: 18px"
color="primary"
icon="wifi"
>....</q-fab>

<!-- Expandable, fixed position on a QLayout -->
<q-fixed-position corner="bottom-right" :offset="[18, 18]">
<q-fab
color="primary"
icon="wifi"
>....</q-fab>
</q-fixed-position>

We’ll continue describing only the expandable FAB, as the non-expandable FAB is, as mentioned above, a simple round button.

Toggle through v-model

<template>
<div>
<q-btn color="primary" @click="open = true">
<q-icon name="menu" />
</q-btn>
<q-btn color="primary" @click="open = false">
<q-icon name="close" />
</q-btn>

<q-fab
v-model="open"
color="primary"
icon="wifi"
>....</q-fab>
</div>
</template>

<script>
export default {
data () {
return {
open: false
}
}
}
</script>

Labeling with Tooltips

Notice slot="tooltip" for the Tooltip on main button and where are the Tooltips placed for the Fab action buttons.

<q-fab
color="primary"
active-icon="alarm"
direction="up"
>
<q-tooltip
slot="tooltip"
anchor="center left"
self="center right"
:offset="[20, 0]"
>
Tooltip in FAB
</q-tooltip>

<q-fab-action color="purple" @click="toast('mail')" icon="mail">
<q-tooltip anchor="center left" self="center right" :offset="[20, 0]">Mail</q-tooltip>
</q-fab-action>
<q-fab-action color="secondary" @click="toast('alarm')" icon="alarm">
<q-tooltip anchor="center left" self="center right" :offset="[20, 0]">Alarm</q-tooltip>
</q-fab-action>
</q-fab>

For more information about Tooltips, please refer to the Tooltip documentation.
