|
<p>Dropdowns are toggleable, contextual overlays for displaying lists of links and more. They’re made interactive with the included Bootstrap dropdown JavaScript plugin. They’re toggled by clicking, not by hovering; this is <a href="https://markdotto.com/2012/02/27/bootstrap-explained-dropdowns/">an intentional design decision</a>.</p>
|
|
<p>Dropdowns are built on a third party library, <a href="https://popper.js.org/">Popper</a>, which provides dynamic positioning and viewport detection. Be sure to include <a href="https://cdn.jsdelivr.net/npm/@popperjs/core@2.5.4/dist/umd/popper.min.js">popper.min.js</a> before Bootstrap’s JavaScript or use <code>bootstrap.bundle.min.js</code> / <code>bootstrap.bundle.js</code> which contains Popper. Popper isn’t used to position dropdowns in navbars though as dynamic positioning isn’t required.</p>

<p>The <a href="https://www.w3.org/TR/wai-aria/"><abbr title="Web Accessibility Initiative">WAI</abbr> <abbr title="Accessible Rich Internet Applications">ARIA</abbr></a> standard defines an actual <a href="https://www.w3.org/WAI/PF/aria/roles#menu"><code>role="menu"</code> widget</a>, but this is specific to application-like menus which trigger actions or functions. <abbr title="Accessible Rich Internet Applications">ARIA</abbr> menus can only contain menu items, checkbox menu items, radio button menu items, radio button groups, and sub-menus.</p>
|
|
<p>Bootstrap’s dropdowns, on the other hand, are designed to be generic and applicable to a variety of situations and markup structures. For instance, it is possible to create dropdowns that contain additional inputs and form controls, such as search fields or login forms. For this reason, Bootstrap does not expect (nor automatically add) any of the <code>role</code> and <code>aria-</code> attributes required for true <abbr title="Accessible Rich Internet Applications">ARIA</abbr> menus. Authors will have to include these more specific attributes themselves.</p>
|
|
<p>However, Bootstrap does add built-in support for most standard keyboard menu interactions, such as the ability to move through individual <code>.dropdown-item</code> elements using the cursor keys and close the menu with the <kbd>ESC</kbd> key.</p>
|
|
<h2 id="examples">Examples</h2>
|
|
<p>Wrap the dropdown’s toggle (your button or link) and the dropdown menu within <code>.dropdown</code>, or another element that declares <code>position: relative;</code>. Dropdowns can be triggered from <code><a></code> or <code><button></code> elements to better fit your potential needs. The examples shown here use semantic <code><ul></code> elements where appropriate, but custom markup is supported.</p>
|
|
<h3 id="single-button">Single button</h3>
|
|
<p>Any single <code>.btn</code> can be turned into a dropdown toggle with some markup changes. Here’s how you can put them to work with either <code><button></code> elements:</p>
|
|
<div class="bd-example">
|
|
<div class="dropdown">
|
|
<button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenuButton" data-bs-toggle="dropdown" aria-expanded="false">

|
|
<ul class="dropdown-menu" aria-labelledby="dropdownMenuButton">

|
|
<p>Similarly, create split button dropdowns with virtually the same markup as single button dropdowns, but with the addition of <code>.dropdown-toggle-split</code> for proper spacing around the dropdown caret.</p>
|
|
<p>We use this extra class to reduce the horizontal <code>padding</code> on either side of the caret by 25% and remove the <code>margin-left</code> that’s added for regular button dropdowns. Those extra changes keep the caret centered in the split button and provide a more appropriately sized hit area next to the main button.</p>

<p>By default, a dropdown menu is automatically positioned 100% from the top and along the left side of its parent. Add <code>.dropdown-menu-end</code> to a <code>.dropdown-menu</code> to right align the dropdown menu. Directions are mirrored when using Bootstrap in RTL, meaning <code>.dropdown-menu-end</code> will appear on the left side.</p>

<h2 id="usage">Usage</h2>
|
|
<p>Via data attributes or JavaScript, the dropdown plugin toggles hidden content (dropdown menus) by toggling the <code>.show</code> class on the parent <code>.dropdown-menu</code>. The <code>data-bs-toggle="dropdown"</code> attribute is relied on for closing dropdown menus at an application level, so it’s a good idea to always use it.</p>
|
|
<div class="bd-callout bd-callout-info">
|
|
On touch-enabled devices, opening a dropdown adds empty <code>mouseover</code> handlers to the immediate children of the <code><body></code> element. This admittedly ugly hack is necessary to work around a <a href="https://www.quirksmode.org/blog/archives/2014/02/mouse_event_bub.html">quirk in iOS' event delegation</a>, which would otherwise prevent a tap anywhere outside of the dropdown from triggering the code that closes the dropdown. Once the dropdown is closed, these additional empty <code>mouseover</code> handlers are removed.
