Dropdowns
Toggle contextual overlays for displaying lists of links and more with the Bootstrap dropdown plugin.
Examples
We created a drop-down
component that can be used to create dropdowns.
You can use the defaul trigger which is an <a>
or change to a custom one via slot="title"
to better fit your potential needs.
<drop-down tag="div">
<button aria-label="Regular" data-toggle="dropdown" class="dropdown-toggle btn-rotate btn btn-secondary"><i></i>
Regular
</button>
<ul class="dropdown-menu">
<a href="#" class="dropdown-item">Action</a>
<a href="#" class="dropdown-item">Another action</a>
<a href="#" class="dropdown-item">Something else here</a>
</ul>
</drop-down>
Dropdown link
<drop-down tag="div">
<button aria-label="Dropdown link" data-toggle="dropdown" class="dropdown-toggle btn-rotate btn btn-secondary">
Dropdown link
</button>
<ul class="dropdown-menu">
<a href="#" class="dropdown-item">Action</a>
<a href="#" class="dropdown-item">Another action</a>
<a href="#" class="dropdown-item">Something else here</a>
</ul>
</drop-down>
Colors
The best part is you can do this with any button variant, too:
<div class="btn-group">
<drop-down tag="div">
<button aria-label="Primary" data-toggle="dropdown" class="dropdown-toggle btn-rotate btn btn-primary">
Primary
</button>
<ul class="dropdown-menu">
<a href="#" class="dropdown-item">Action</a>
<a href="#" class="dropdown-item">Another action</a>
<a href="#" class="dropdown-item">Something else here</a>
<div class="dropdown-divider"></div>
<a href="#" class="dropdown-item">Separated link</a>
</ul>
</drop-down>
<drop-down tag="div">
<button aria-label="Secondary" data-toggle="dropdown" class="dropdown-toggle btn-rotate btn btn-secondary">
Secondary
</button>
<ul class="dropdown-menu">
<a href="#" class="dropdown-item">Action</a>
<a href="#" class="dropdown-item">Another action</a>
<a href="#" class="dropdown-item">Something else here</a>
<div class="dropdown-divider"></div>
<a href="#" class="dropdown-item">Separated link</a>
</ul>
</drop-down>
<drop-down tag="div">

<a href="#" class="dropdown-item">Something else here</a>
<div class="dropdown-divider"></div>
<a href="#" class="dropdown-item">Separated link</a>
</ul>
</drop-down>
<drop-down tag="div">
<button aria-label="Warning" data-toggle="dropdown" class="dropdown-toggle btn-rotate btn btn-warning">

</button>
<ul class="dropdown-menu">
<a href="#" class="dropdown-item">Action</a>
<a href="#" class="dropdown-item">Another action</a>
<a href="#" class="dropdown-item">Something else here</a>
<div class="dropdown-divider"></div>
<a href="#" class="dropdown-item">Separated link</a>
</ul>
</drop-down>
<drop-down tag="div">
<button aria-label="Danger" data-toggle="dropdown" class="dropdown-toggle btn-rotate btn btn-danger">
Danger
</button>
<ul class="dropdown-menu">
<a href="#" class="dropdown-item">Action</a>
<a href="#" class="dropdown-item">Another action</a>
<a href="#" class="dropdown-item">Something else here</a>
<div class="dropdown-divider"></div>
<a href="#" class="dropdown-item">Separated link</a>
</ul>
</drop-down>
</div>
Split button dropdowns
Similarly, create split button dropdowns with virtually the same markup as single button dropdowns, but with the addition of .dropdown-toggle-split for proper spacing around the dropdown caret. We use this extra class to reduce the horizontal padding on either side of the caret by 25% and remove the margin-left 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
<div>
<drop-down class="btn-group">
<button type="button" class="btn btn-danger">Action</button>
<button type="button" class="btn dropdown-toggle dropdown-toggle-split btn-danger" data-toggle="dropdown" aria-haspopup="true">
<span class="sr-only">Toggle Dropdown</span>
</button>
<ul class="dropdown-menu">
<a href="#" class="dropdown-item">Action</a>
<a href="#" class="dropdown-item">Another action</a>
<a href="#" class="dropdown-item">Something else here</a>
<div class="dropdown-divider"></div>
<a href="#" class="dropdown-item">Separated link</a>
</ul>
</drop-down>
</div>
Dropup variation
Trigger dropdown menus above elements by adding .dropup
to the parent element.
<drop-down tag="div" class="dropup">
<button aria-label="Dropup" data-toggle="dropdown" class="dropdown-toggle btn-rotate btn btn-secondary"><i></i>
Dropup
</button> <ul class="dropdown-menu"><a href="#" class="dropdown-item">Action</a> <a href="#" class="dropdown-item">Another action</a> <a href="#" class="dropdown-item">Something else here</a></ul>
</drop-down>
Colors
Set for the menu-classes
to .dropdown-black
class to change the drodown background’s color.
<drop-down tag="div">
<button aria-label="Black menu" data-toggle="dropdown" class="dropdown-toggle btn-rotate btn btn-secondary">
Black menu
</button>
<ul class="dropdown-menu dropdown-black">
<h6 class="dropdown-header">Dropdown header</h6>
<a href="#" class="dropdown-item">Action</a>
<a href="#" class="dropdown-item">Another action</a>
<a href="#" class="dropdown-item">Something else here</a>
</ul>
</drop-down>
