Popovers are small overlays with a title and a few lines of content, opened by click, hover or focus. Use them for hints, definitions and details that do not deserve a whole dialog; the examples cover placements, triggers, disabled elements, custom styles and real interface spots.
1Basic popover
Click the button to toggle a popover with a title and content.
<button type="button" class="btn btn-lg btn-danger" data-ui-toggle="popover" data-ui-title="About Fluxio Works" data-ui-content="Friendly people answer your questions quickly, by phone, chat or email.">Click to toggle popover</button>2Four directions
<code>data-ui-placement</code> chooses top, right, bottom or left.
<div class="d-flex flex-wrap gap-2">
<button type="button" class="btn btn-secondary" data-ui-toggle="popover" data-ui-content="Popover on the top." data-ui-placement="top">Popover on top</button>
<button type="button" class="btn btn-secondary" data-ui-toggle="popover" data-ui-content="Popover on the right." data-ui-placement="right">Popover on right</button>
<button type="button" class="btn btn-secondary" data-ui-toggle="popover" data-ui-content="Popover on the bottom." data-ui-placement="bottom">Popover on bottom</button>
<button type="button" class="btn btn-secondary" data-ui-toggle="popover" data-ui-content="Popover on the left." data-ui-placement="left">Popover on left</button>
</div>3Dismiss on next click
<code>data-ui-trigger="focus"</code> closes the popover when the user clicks anywhere else. Use an <code>a</code> with <code>tabindex</code>.
<a tabindex="0" class="btn btn-outline-danger" role="button" data-ui-toggle="popover" data-ui-title="Dismissible popover" data-ui-content="Click anywhere to close me." data-ui-trigger="focus">Dismissible popover</a>4Hover trigger
<code>data-ui-trigger="hover focus"</code> opens on mouse hover and on keyboard focus.
<button type="button" class="btn btn-outline-primary" data-ui-toggle="popover" data-ui-title="Quick facts" data-ui-content="Lifetime access is included in every plan." data-ui-trigger="hover focus"><i class="bi bi-cursor" aria-hidden="true"></i> Hover me</button>5Disabled element
Disabled buttons do not fire events, so wrap them in a focusable span that carries the popover.
<span class="d-inline-block" tabindex="0" data-ui-toggle="popover" data-ui-trigger="hover focus" data-ui-content="Finish your profile to unlock this.">
<button class="btn btn-primary" type="button" disabled>Disabled button</button>
</span>6In running text
A popover on an inline link explains a term without leaving the sentence.
Every order includes career coaching at no extra cost, and you can cancel at any time.

Leave out <code>data-ui-title</code> for a popover without a header.
<button type="button" class="btn btn-outline-secondary" data-ui-toggle="popover" data-ui-content="Try the first lesson of any course for free before you decide." data-ui-placement="bottom">No title</button>9Custom style
