<h2 id="overview">Overview</h2>
<p>Things to know when using the popover plugin:</p>
<ul>
<li>Popovers rely on the 3rd party library <a href="https://popper.js.org/">Popper</a> for positioning. You must include <a href="https://cdn.jsdelivr.net/npm/@popperjs/core@2.5.4/dist/umd/popper.min.js">popper.min.js</a> before bootstrap.js or use <code>bootstrap.bundle.min.js</code> / <code>bootstrap.bundle.js</code> which contains Popper in order for popovers to work!</li>
<li>Popovers require the <a href="/docs/5.0/components/tooltips/">tooltip plugin</a> as a dependency.</li>
<li>Popovers are opt-in for performance reasons, so <strong>you must initialize them yourself</strong>.</li>
<li>Zero-length <code>title</code> and <code>content</code> values will never show a popover.</li>
<li>Specify <code>container: 'body'</code> to avoid rendering problems in more complex components (like our input groups, button groups, etc).</li>
<li>Triggering popovers on hidden elements will not work.</li>
<li>Popovers for <code>.disabled</code> or <code>disabled</code> elements must be triggered on a wrapper element.</li>
<li>When triggered from anchors that wrap across multiple lines, popovers will be centered between the anchors' overall width. Use <code>.text-nowrap</code> on your <code>&lt;a&gt;</code>s to avoid this behavior.</li>
<li>Popovers must be hidden before their corresponding elements have been removed from the DOM.</li>
<li>Popovers can be triggered thanks to an element inside a shadow DOM.</li>
</ul>
<div class="bd-callout bd-callout-info">
The animation effect of this component is dependent on the <code>prefers-reduced-motion</code> media query. See the <a href="/docs/5.0/getting-started/accessibility/#reduced-motion">reduced motion section of our accessibility documentation</a>.
</div>
<p>Keep reading to see how popovers work with some examples.</p>
<h2 id="example-enable-popovers-everywhere">Example: Enable popovers everywhere</h2>
<p>One way to initialize all popovers on a page would be to select them by their <code>data-bs-toggle</code> attribute:</p>
<div class="highlight"><pre class="chroma"><code class="language-js" data-lang="js"><span class="kd">var</span> <span class="nx">popoverTriggerList</span> <span class="o">=</span> <span class="p">[].</span><span class="nx">slice</span><span class="p">.</span><span class="nx">call</span><span class="p">(</span><span class="nb">document</span><span class="p">.</span><span class="nx">querySelectorAll</span><span class="p">(</span><span class="s1">&#39;[data-bs-toggle=&#34;popover&#34;]&#39;</span><span class="p">))</span>

<span class="p">})</span>
</code></pre></div><h2 id="example-using-the-container-option">Example: Using the <code>container</code> option</h2>
<p>When you have some styles on a parent element that interfere with a popover, you&rsquo;ll want to specify a custom <code>container</code> so that the popover&rsquo;s HTML appears within that element instead.</p>
<div class="highlight"><pre class="chroma"><code class="language-js" data-lang="js"><span class="kd">var</span> <span class="nx">popover</span> <span class="o">=</span> <span class="k">new</span> <span class="nx">bootstrap</span><span class="p">.</span><span class="nx">Popover</span><span class="p">(</span><span class="nb">document</span><span class="p">.</span><span class="nx">querySelector</span><span class="p">(</span><span class="s1">&#39;.example-popover&#39;</span><span class="p">),</span> <span class="p">{</span>

<p>Elements with the <code>disabled</code> attribute aren&rsquo;t interactive, meaning users cannot hover or click them to trigger a popover (or tooltip).

<p>For disabled popover triggers, you may also prefer <code>data-bs-trigger=&quot;hover&quot;</code> so that the popover appears as immediate visual feedback to your users as they may not expect to <em>click</em> on a disabled element.</p>

<h3 id="making-popovers-work-for-keyboard-and-assistive-technology-users">Making popovers work for keyboard and assistive technology users</h3>
<p>To allow keyboard users to activate your popovers, you should only add them to HTML elements that are traditionally keyboard-focusable and interactive (such as links or form controls). Although arbitrary HTML elements (such as <code>&lt;span&gt;</code>s) can be made focusable by adding the <code>tabindex=&quot;0&quot;</code> attribute, this will add potentially annoying and confusing tab stops on non-interactive elements for keyboard users, and most assistive technologies currently do not announce the popover&rsquo;s content in this situation. Additionally, do not rely solely on <code>hover</code> as the trigger for your popovers, as this will make them impossible to trigger for keyboard users.</p>
<p>While you can insert rich, structured HTML in popovers with the <code>html</code> option, we strongly recommend that you avoid adding an excessive amount of content. The way popovers currently work is that, once displayed, their content is tied to the trigger element with the <code>aria-describedby</code> attribute. As a result, the entirety of the popover&rsquo;s content will be announced to assistive technology users as one long, uninterrupted stream.</p>
<p>Additionally, while it is possible to also include interactive controls (such as form elements or links) in your popover (by adding these elements to the <code>allowList</code> of allowed attributes and tags), be aware that currently the popover does not manage keyboard focus order. When a keyboard user opens a popover, focus remains on the triggering element, and as the popover usually does not immediately follow the trigger in the document&rsquo;s structure, there is no guarantee that moving forward/pressing <kbd>TAB</kbd> will move a keyboard user into the popover itself. In short, simply adding interactive controls to a popover is likely to make these controls unreachable/unusable for keyboard users and users of assistive technologies, or at the very least make for an illogical overall focus order. In these cases, consider using a modal dialog instead.</p>
</div>

<p>Options can be passed via data attributes or JavaScript. For data attributes, append the option name to <code>data-bs-</code>, as in <code>data-bs-animation=&quot;&quot;</code>.</p>
