Popovers
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 Nimbus" data-ui-content="Clear prices, honest advice and no surprises along the way.">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="Free cancellation 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 airport transfers at no extra cost, and you can cancel at any time.
<p class="mb-0">Every order includes <a tabindex="0" class="link-primary text-decoration-underline" role="button" data-ui-toggle="popover" data-ui-title="Car rental" data-ui-content="Friendly people answer your questions quickly, by phone, chat or email." data-ui-trigger="focus">airport transfers</a> at no extra cost, and you can cancel at any time.</p>7Help icon
A small round icon button next to a heading opens a hint.
Monthly budget
<div class="d-flex align-items-center gap-2">
<h3 class="h6 mb-0">Monthly budget</h3>
<button type="button" class="btn btn-link p-0 link-secondary" data-ui-toggle="popover" data-ui-title="How it works" data-ui-content="We sum all invoices that are due this month." data-ui-placement="right" aria-label="Help"><i class="bi bi-question-circle" aria-hidden="true"></i></button>
</div>8Content only
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="We keep things simple, so you can focus on what matters to you." data-ui-placement="bottom">No title</button>9Custom style
<code>data-ui-custom-class</code> adds a class to the popover so you can theme it.
<button type="button" class="btn btn-primary" data-ui-toggle="popover" data-ui-title="Branded popover" data-ui-content="Uses the template primary colour." data-ui-custom-class="cb-popover">Custom popover</button>10Status buttons

Popovers on buttons of a button group give each tool a short explanation.

</div>19Escape a scrolling box
<code>data-ui-container="body"</code> renders the popover outside an <code>overflow</code> container so it is not cut off.
Local guides show you the places that never make it into guidebooks.
We measure success by how many travellers come back and tell their friends.
<div class="border rounded p-3 overflow-auto" style="max-height:90px">
