Dropdowns
Toggle contextual overlays for displaying lists of links and more with the Bootstrap dropdown plugin.
Example
<div class="dropdown"> <button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenuButton1" data-bs-toggle="dropdown" aria-expanded="false"> Dropdown button </button> <ul class="dropdown-menu" aria-labelledby="dropdownMenuButton1"> <li><a class="dropdown-item" href="#">Action</a></li> <li><a class="dropdown-item" href="#">Another action</a></li> <li><a class="dropdown-item" href="#">Something else here</a></li> </ul></div>Split button
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 class="btn-group"> <button type="button" class="btn btn-danger">Action</button> <button type="button" class="btn btn-danger dropdown-toggle dropdown-toggle-split" data-bs-toggle="dropdown" aria-expanded="false"> <span class="visually-hidden">Toggle Dropdown</span> </button> <ul class="dropdown-menu"> <li><a class="dropdown-item" href="#">Action</a></li> <li><a class="dropdown-item" href="#">Another action</a></li> <li><a class="dropdown-item" href="#">Something else here</a></li> <li><hr class="dropdown-divider"></li> <li><a class="dropdown-item" href="#">Separated link</a></li> </ul></div>Dark dropdowns
Opt into darker dropdowns to match a dark navbar or custom style by adding .dropdown-menu-dark onto an existing .dropdown-menu. No changes are required to the dropdown items.
And putting it to use in a navbar:
<div class="dropdown"> <button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenuButton2" data-bs-toggle="dropdown" aria-expanded="false"> Dropdown button </button> <ul class="dropdown-menu dropdown-menu-dark" aria-labelledby="dropdownMenuButton2"> <li><a class="dropdown-item active" href="#">Action</a></li> <li><a class="dropdown-item" href="#">Another action</a></li> <li><a class="dropdown-item" href="#">Something else here</a></li> <li><hr class="dropdown-divider"></li> <li><a class="dropdown-item" href="#">Separated link</a></li> </ul></div>Directions
<div class="dropdown-center"> <button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownCenterBtn" data-bs-toggle="dropdown" aria-expanded="false"> Centered dropdown </button> <ul class="dropdown-menu" aria-labelledby="dropdownCenterBtn"> <li><a class="dropdown-item" href="#">Action</a></li> <li><a class="dropdown-item" href="#">Action two</a></li> <li><a class="dropdown-item" href="#">Action three</a></li> </ul></div>Dropup
Trigger dropdown menus above elements by adding .dropup to the parent element.
<ul class="d-flex gap g-3"> <li> <!-- Default dropup button --> <div class="btn-group dropup"> <button type="button" class="btn btn-secondary dropdown-toggle" data-bs-toggle="dropdown" aria-expanded="false"> Dropup </button> <ul class="dropdown-menu"> <li><a class="dropdown-item" href="#">Action</a></li> <li><a class="dropdown-item" href="#">Action two</a></li> <li><a class="dropdown-item" href="#">Action three</a></li> </ul> </div> </li> <li> <!-- Split dropup button --> <div class="btn-group dropup"> <button type="button" class="btn btn-secondary"> Split dropup </button> <button type="button" class="btn btn-secondary dropdown-toggle dropdown-toggle-split" data-bs-toggle="dropdown" aria-expanded="false"> <span class="visually-hidden">Toggle Dropdown</span> </button> <ul class="dropdown-menu"> <li><a class="dropdown-item" href="#">Action</a></li> <li><a class="dropdown-item" href="#">Action two</a></li> <li><a class="dropdown-item" href="#">Action three</a></li> </ul> </div> </li></ul>Dropup centered
Make the dropup menu centered above the toggle with .dropup-center on the parent element.
<div class="dropup-center dropup"> <button class="btn btn-secondary dropdown-toggle" type="button" id="dropupCenterBtn" data-bs-toggle="dropdown" aria-expanded="false"> Centered dropup </button> <ul class="dropdown-menu" aria-labelledby="dropupCenterBtn"> <li><a class="dropdown-item" href="#">Action</a></li> <li><a class="dropdown-item" href="#">Action two</a></li> <li><a class="dropdown-item" href="#">Action three</a></li> </ul></div>Dropend

Put a form within a dropdown menu, or make it into a dropdown menu, and use margin or padding utilities to give it the negative space you require.
<div class="dropdown-menu position-static d-block"> <form class="px-4 py-3"> <div class="mb-3"> <label for="exampleDropdownFormEmail1" class="form-label">Email address</label> <input type="email" class="form-control" id="exampleDropdownFormEmail1" placeholder="email@example.com"> </div> <div class="mb-3"> <label for="exampleDropdownFormPassword1" class="form-label">Password</label> <input type="password" class="form-control" id="exampleDropdownFormPassword1" placeholder="Password"> </div> <div class="mb-3"> <div class="form-check form-check-sm"> <input type="checkbox" class="form-check-input" id="dropdownCheck"> <label class="form-check-label" for="dropdownCheck"> Remember me </label> </div> </div> <button type="submit" class="btn btn-primary">Sign in</button> </form> <div class="dropdown-divider"></div> <a class="dropdown-item" href="#">New around here? Sign up</a> <a class="dropdown-item" href="#">Forgot password?</a></div>Dropdown options
Use data-bs-offset or data-bs-reference to change the location of the dropdown.
<ul class="d-flex flex-wrap gap g-3"> <li> <div class="dropdown"> <button type="button" class="btn btn-secondary dropdown-toggle" id="dropdownMenuOffset" data-bs-toggle="dropdown" aria-expanded="false" data-bs-offset="10,20"> Offset </button> <ul class="dropdown-menu" aria-labelledby="dropdownMenuOffset"> <li><a class="dropdown-item" href="#">Action</a></li> <li><a class="dropdown-item" href="#">Another action</a></li> <li><a class="dropdown-item" href="#">Something else here</a></li> </ul> </div> </li> <li> <div class="btn-group"> <button type="button" class="btn btn-secondary">Reference</button> <button type="button" class="btn btn-secondary dropdown-toggle dropdown-toggle-split" id="dropdownMenuReference" data-bs-toggle="dropdown" aria-expanded="false" data-bs-reference="parent"> <span class="visually-hidden">Toggle Dropdown</span> </button> <ul class="dropdown-menu" aria-labelledby="dropdownMenuReference"> <li><a class="dropdown-item" href="#">Action</a></li> <li><a class="dropdown-item" href="#">Another action</a></li> <li><a class="dropdown-item" href="#">Something else here</a></li> <li><hr class="dropdown-divider"></li> <li><a class="dropdown-item" href="#">Separated link</a></li> </ul> </div> </li></ul>Auto close behavior
By default, the dropdown menu is closed when clicking inside or outside the dropdown menu. You can use the autoClose option to change this behavior of the dropdown.
<ul class="d-flex flex-wrap gap g-3"> <li> <div class="btn-group"> <button class="btn btn-secondary dropdown-toggle" type="button" id="defaultDropdown" data-bs-toggle="dropdown" data-bs-auto-close="true" aria-expanded="false"> Default dropdown </button> <ul class="dropdown-menu" aria-labelledby="defaultDropdown"> <li><a class="dropdown-item" href="#">Menu item</a></li> <li><a class="dropdown-item" href="#">Menu item</a></li> <li><a class="dropdown-item" href="#">Menu item</a></li> </ul> </div> </li> <li> <div class="btn-group"> <button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenuClickableOutside" data-bs-toggle="dropdown" data-bs-auto-close="inside" aria-expanded="false"> Clickable outside </button> <ul class="dropdown-menu" aria-labelledby="dropdownMenuClickableOutside"> <li><a class="dropdown-item" href="#">Menu item</a></li> <li><a class="dropdown-item" href="#">Menu item</a></li> <li><a class="dropdown-item" href="#">Menu item</a></li> </ul> </div> </li> <li> <div class="btn-group"> <button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenuClickableInside" data-bs-toggle="dropdown" data-bs-auto-close="outside" aria-expanded="false"> Clickable inside </button> <ul class="dropdown-menu" aria-labelledby="dropdownMenuClickableInside"> <li><a class="dropdown-item" href="#">Menu item</a></li> <li><a class="dropdown-item" href="#">Menu item</a></li> <li><a class="dropdown-item" href="#">Menu item</a></li> </ul> </div> </li> <li> <div class="btn-group"> <button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenuClickable" data-bs-toggle="dropdown" data-bs-auto-close="false" aria-expanded="false"> Manual close </button> <ul class="dropdown-menu" aria-labelledby="dropdownMenuClickable"> <li><a class="dropdown-item" href="#">Menu item</a></li> <li><a class="dropdown-item" href="#">Menu item</a></li> <li><a class="dropdown-item" href="#">Menu item</a></li> </ul> </div> </li> </ul>
