Dropdown
A dropdown is a menu that opens from a button or a link and holds options or actions, so the toolbar stays short.
Default dropdown
Any .btn becomes a dropdown toggle with data-bs-toggle="dropdown" and a .dropdown-menu next to it. The classes below add dividers, headers, icons and other details to the menu.
<div class="dropdown">
<a href="#" class="btn dropdown-toggle" data-bs-toggle="dropdown">Open dropdown</a>
<div class="dropdown-menu">
<a class="dropdown-item" href="#">Action</a>
<a class="dropdown-item" href="#">Another action</a>
<a class="dropdown-item" href="#">Third action</a>
</div>
</div>Dropdown divider
A .dropdown-divider separates groups of items.
<div class="dropdown">

<div class="dropdown-menu">
<a class="dropdown-item" href="#">Action</a>
<a class="dropdown-item" href="#">Another action</a>
<div class="dropdown-divider"></div>
<a class="dropdown-item" href="#">Separated link</a>
</div>
</div>Active state
The active class marks the current item.
<div class="dropdown">
<a href="#" class="btn dropdown-toggle" data-bs-toggle="dropdown">Open dropdown</a>
<div class="dropdown-menu">
<a class="dropdown-item" href="#">Action</a>
<a class="dropdown-item" href="#">Another action</a>
<a class="dropdown-item active" href="#">Active action</a>
</div>
</div>Disabled state

<a href="#" class="btn dropdown-toggle" data-bs-toggle="dropdown">Open dropdown</a>
<div class="dropdown-menu">
<span class="dropdown-header">Dropdown header</span>
<a class="dropdown-item" href="#">Action</a>
<a class="dropdown-item" href="#">Another action</a>
</div>
</div>Dropdown with icons
An icon in front of each item makes the options faster to scan.

</a>
</div>
</div>Dropdown with checkboxes
Items can hold checkboxes, which makes a dropdown work as a filter.
<div class="dropdown">

<div class="dropdown-menu">
<label class="dropdown-item">

</div>Dropdown with card content
A menu can hold card content, such as a short profile or a summary, when a plain list isn't enough.
<div class="dropdown">

<div class="dropdown-menu dropdown-menu-card" style="max-width: 16rem">

</div>Multi-column menu
A long menu can be split into columns instead of scrolling. Wrap the items in dropdown-menu-columns, then group them into dropdown-menu-column elements - one per column.
<div class="dropdown">
<button class="btn dropdown-toggle" type="button" data-bs-toggle="dropdown" aria-expanded="false">Components</button>
<div class="dropdown-menu">
<div class="dropdown-menu-columns">
<div class="dropdown-menu-column">
<a class="dropdown-item" href="#">Accordion</a>
<a class="dropdown-item" href="#">Alert</a>
<a class="dropdown-item" href="#">Avatar</a>
</div>
<div class="dropdown-menu-column">
<a class="dropdown-item" href="#">Badge</a>
<a class="dropdown-item" href="#">Button</a>
<a class="dropdown-item" href="#">Card</a>
</div>
</div>
</div>
</div>Submenu
Nest a dropdown inside a menu item and add dropend to open the child menu to the side instead of below.
<div class="dropdown">
<button class="btn dropdown-toggle" type="button" data-bs-toggle="dropdown" aria-expanded="false">Actions</button>
<div class="dropdown-menu">
<a class="dropdown-item" href="#">Edit</a>
<div class="dropdown dropend">
<a class="dropdown-item dropdown-toggle" href="#" data-bs-toggle="dropdown" aria-expanded="false">Move to</a>
<div class="dropdown-menu">
<a class="dropdown-item" href="#">Inbox</a>
<a class="dropdown-item" href="#">Archive</a>
</div>
</div>
<a class="dropdown-item" href="#">Delete</a>
</div>
</div>JavaScript
Tabler automatically initializes all elements with data-bs-toggle="dropdown" on page load. This is the code that runs:
const dropdownTriggerList: HTMLElement[] = [].slice.call(document.querySelectorAll<HTMLElement>('[data-bs-toggle="dropdown"]'))
dropdownTriggerList.map(function (dropdownTriggerEl: HTMLElement) {
const options = {
boundary: dropdownTriggerEl.getAttribute('data-bs-boundary') === 'viewport' ? document.documentElement : 'clippingParents',
}
return new Dropdown(dropdownTriggerEl, options)
})Accessibility
- The trigger must be a
button, or anawith anhref. Bootstrap togglesaria-expandedon it for you, so do not set it by hand. - Bootstrap moves focus into the menu and supports the arrow keys, Home, End and Escape. That only works while the items are
.dropdown-itemelements inside.dropdown-menu. - An icon-only trigger needs an
aria-label. The caret is decorative and carries no name. - A dropdown used as a menu of actions should hold
buttonitems; one used for navigation should hold links. Mixing them makes the keyboard behavior inconsistent. - Use
.dropdown-headerfor a group title and.dropdown-dividerfor a separator, rather than styling a plain item to look like one.
