Dropdowns

Bootstrap 5 Dropdown component

Responsive dropdown/caret built with Bootstrap 5. Examples of navbar dropdown, dropdown list, submenu, dropdown toggle, dropdown hover, hamburger icon & more.

Dropdowns are responsible for toggleable (collapsible) display a list of links.

Toggle contextual overlays for displaying lists of links and more with the MDB dropdown plugin.

Note: Read the API tab to find all available options and advanced customization

Basic examples

Wrap the dropdown’s toggle (your button or link) and the dropdown menu within .dropdown element that declares position: relative;. Dropdowns can be triggered from <a> or <button> elements to better fit your potential needs. The examples shown here use semantic <ul> elements where appropriate, but custom markup is supported.

Regular button

Any single .btn can be turned into a dropdown toggle with some markup changes. Here’s how you can put them to work with either <button> elements:

              <div class="dropdown">
                <button
                  class="btn btn-primary dropdown-toggle"
                  type="button"
                  id="dropdownMenuButton"
                  data-mdb-toggle="dropdown"
                  aria-expanded="false"
                >
                  Dropdown button
                </button>
                <ul class="dropdown-menu" aria-labelledby="dropdownMenuButton">
                  <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>

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.

Dropleft

Trigger dropdown menus at the left of the elements by adding .dropstart to the parent element.

Menu items

You can use <a> or <button> elements as dropdown items.

Edit in sandbox 
        
            
            <div class="dropdown">
              <button class="btn btn-primary dropdown-toggle" type="button" id="dropdownMenu2" data-mdb-toggle="dropdown" aria-expanded="false">
                Dropdown
              </button>
              <ul class="dropdown-menu" aria-labelledby="dropdownMenu2">
                <li><button class="dropdown-item" type="button">Action</button></li>
                <li><button class="dropdown-item" type="button">Another action</button></li>
                <li><button class="dropdown-item" type="button">Something else here</button></li>
              </ul>
            </div>

You can also create non-interactive dropdown items with .dropdown-item-text. Feel free to style further with custom CSS or text utilities.

Edit in sandbox 
        
            
            <ul class="dropdown-menu">
              <li><span class="dropdown-item-text">Dropdown item text</span></li>
              <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>

Active

Add .active to items in the dropdown to style them as active. To convey the active state to assistive technologies, use the aria-current attribute — using the page value for the current page, or true for the current item in a set.

              <ul class="dropdown-menu">

                <li><a class="dropdown-item active" href="#" aria-current="true">Active link</a></li>
                <li><a class="dropdown-item" href="#">Another link</a></li>
              </ul>

Disabled

Add .disabled to items in the dropdown to style them as disabled.

Edit in sandbox 
        
            
              <ul class="dropdown-menu">
                <li><a class="dropdown-item" href="#">Regular link</a></li>
                <li><a class="dropdown-item disabled">Disabled link</a></li>
                <li><a class="dropdown-item" href="#">Another link</a></li>
              </ul>

Menu alignment

By default, a dropdown menu is automatically positioned 100% from the top and along the left side of its parent. Add .dropdown-menu-end to a .dropdown-menu to right align the dropdown menu.

Edit in sandbox 
        
            
            <div class="btn-group">
              <button type="button" class="btn btn-primary dropdown-toggle" data-mdb-toggle="dropdown" aria-expanded="false">
                Right-aligned menu
              </button>
              <ul class="dropdown-menu dropdown-menu-end">
                <li><button class="dropdown-item" type="button">Action</button></li>
                <li><button class="dropdown-item" type="button">Another action</button></li>
                <li><button class="dropdown-item" type="button">Something else here</button></li>
              </ul>
            </div>

Responsive alignment

If you want to use responsive alignment, disable dynamic positioning by adding the data-mdb-display="static" attribute and use the responsive variation classes.

To align right the dropdown menu with the given breakpoint or larger, add .dropdown-menu{-sm|-md|-lg|-xl|-xxl}-end.

                  <li><button class="dropdown-item" type="button">Action</button></li>
                  <li><button class="dropdown-item" type="button">Another action</button></li>
                  <li><button class="dropdown-item" type="button">Something else here</button></li>
                </ul>
              </div>

To align left the dropdown menu with the given breakpoint or larger, add .dropdown-menu-end and .dropdown-menu{-sm|-md|-lg|-xl|-xxl}-start.

              <div class="btn-group">

                  type="button"
                  class="btn btn-primary dropdown-toggle"
                  data-mdb-toggle="dropdown"
                  data-mdb-display="static"
                  aria-expanded="false"
                >
                  Right-aligned but left aligned when large screen
                </button>
                <ul class="dropdown-menu dropdown-menu-end dropdown-menu-lg-start">
                  <li><button class="dropdown-item" type="button">Action</button></li>
                  <li><button class="dropdown-item" type="button">Another action</button></li>
                  <li><button class="dropdown-item" type="button">Something else here</button></li>
                </ul>
              </div>

Note that you don’t need to add a data-mdb-display="static" attribute to dropdown buttons in navbars, since Popper isn’t used in navbars.

              </ul>

Text

Place any freeform text within a dropdown menu with text and use spacing utilities. Note that you’ll likely need additional sizing styles to constrain the menu width.

Some example text that's free-flowing within the dropdown menu.

And this is more example text.

Edit in sandbox

                <p class="mb-0">And this is more example text.</p>
              </div>

Forms

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.

Dropdowns - API

Usage

Via data attributes or JavaScript, the dropdown plugin toggles hidden content (dropdown menus) by toggling the .show class on the parent list item. The data-mdb-toggle="dropdown" attribute is relied on for closing dropdown menus at an application level, so it’s a good idea to always use it.

Note:
On touch-enabled devices, opening a dropdown adds empty mouseover handlers to the immediate children of the <body> element. This admittedly ugly hack is necessary to work around a quirk in iOS’ event delegation, 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 mouseover handlers are removed.

Via data attributes

Add data-mdb-toggle="dropdown" to a link or button to toggle a dropdown.

Edit in sandbox 
        
            
            <div class="dropdown">
              <button id="dLabel" type="button" data-mdb-toggle="dropdown" aria-expanded="false">
                Dropdown trigger
              </button>
              <ul class="dropdown-menu" aria-labelledby="dLabel">
                ...
              </ul>
            </div>

Via JavaScript

Call the dropdowns via JavaScript:

Edit in sandbox 
        
            
            const dropdownElementList = [].slice.call(document.querySelectorAll('.dropdown-toggle'));
            const dropdownList = dropdownElementList.map((dropdownToggleEl) => {
              return new mdb.Dropdown(dropdownToggleEl);
            });

data-mdb-toggle="dropdown" still required:
Regardless of whether you call your dropdown via JavaScript or instead use the data-mdb-api, data-mdb-toggle="dropdown" is always required to be present on the dropdown’s trigger element.

Options

Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-mdb-, as in data-mdb-offset="".

Name Type Default Description
autoClose boolean | string true

Configure the auto close behavior of the dropdown:

  • trueclicking outside or inside the dropdown menu.
  • false hidelso will not be closed by pressing esc key)
  • 'inside' - the dropdown will be closed (only) by clicking inside the dropdown menu.
  • 'outside' - the dropdown will be closed (only) by clicking outside the dropdown menu.
boundary string | element 'clippingParents' Overflow constraint boundary of the dropdown menu (applies only to Popper's preventOverflow modifier). By default it's 'clippingParents' and can accept an HTMLElement reference (via JavaScript only). For more information refer to Popper's detectOverflow docs.
display string 'dynamic' By default, we use Popper for dynamic positioning. Disable this with static.
dropdownAnimation string 'on' Turn on / off dropdown animation.
offset array | string | function 0

Offset of the dropdown relative to its target.

When a function is used to determine the offset, it is called with an object containing the offset data as its first argument. The function must return an object with the same structure. The triggering element DOM node is passed as the second argument.

For more information refer to Popper's offset docs.

popperConfig null | object | function null

To change Bootstrap's default Popper config, see Popper's configuration.

When a function is used to create the Popper configuration, it's called with an object that contains the Bootstrap's default Popper configuration. It helps you use and merge the default with your own configuration. The function must return a configuration object for Popper.

reference string | element | object 'toggle' Reference element of the dropdown menu. Accepts the values of 'toggle', 'parent', an HTMLElement reference or an object providing getBoundingClientRect. For more information refer to Popper's constructor docs and virtual element docs.

Note when boundary is set to any value other than 'scrollParent', the style position: static is applied to the .dropdown container.

Edit in sandbox 
        
            
            const myDropdown = document.getElementById('myDropdown');
            const myDropdownInstance = new mdb.Dropdown(myDropdown);
            myDropdownInstance.show();

Events

All dropdown events are fired at the toggling element and then bubbled up. So you can also add event listeners on the .dropdown-menu’s parent element. hide.mdb.dropdown and hidden.mdb.dropdown events have a clickEvent property (only when the original Event type is click) that contains an Event Object for the click event.

Method Description
show.mdb.dropdown Fires immediately when the show instance method is called.
shown.mdb.dropdown Fired when the dropdown has been made visible to the user and CSS transitions have completed.
hide.mdb.dropdown Fires immediately when the hide instance method has been called.
hidden.mdb.dropdown Fired when the dropdown has finished being hidden from the user and CSS transitions have completed.
Edit in sandbox

              // do something...
            });
