Popover
QPopover should be used when you want a menu (or any content) to be displayed on a popup as a result of user clicking/tapping on a DOM element / component.
Installation
Edit /quasar.conf.js
:framework: {
components: ['QPopover'],
// optional if you want to use
// directive `v-close-overlay`
directives: ['CloseOverlay']
}
Basic Usage
In the example below we use a Button (as a target) and when clicking/tapping on it Quasar will display a List.
You can replace the QBtn and the List with any DOM elements or components you like.<!--
The target button (can be anything else)
must be direct parent of QPopover on the
DOM hierarchy.
-->
<q-btn label="Email">
<!-- Direct child of target -->
<q-popover>
<!--
The DOM element(s) that make up the popup,
in this case a list:
-->
<q-list separator link>
<!-- notice `v-close-overlay` which closes popover -->
<q-item v-close-overlay @click.native="doSomething">
...
</q-item>
</q-list>
</q-popover>
</q-btn>
The idea is to place QPopover inside your DOM element / component that you want to be the trigger as direct child. Don’t worry about QPopover content inheriting CSS from the container as the QPopover will be injected as a direct child of <body>
.
IMPORTANT
When on a browser, hitting the <ESCAPE> key also closes the QPopover.

Handling Popover Dismissal
By default, clicking/tapping outside the QPopover content will close it. But if you’d like elements from the QPopover content to close it, then use the v-close-overlay
Quasar directive.
Handling Positioning
Position of the QPopover can be customized. It keeps account of the optional anchor
and self
Vue properties. See the demo and play with them.
The final position of the QPopover popup is calculated so that it will be displayed on the available screen real estate, switching to right-side and/or top-side when necessary.
If you would like the QPopover to appear from the touch/click point triggering the QPopover open, then use the Boolean touch-position
Vue property:<q-popover touch-position>
...
</q-popover>
The demo has touch-position
specified for the big image on the center of the page.
