UI Toolkit


Modals are streamlined, but flexible, dialog prompts with the minimum required functionality and smart defaults.

Due to how HTML5 defines its semantics, the autofocus HTML attribute has no effect in Bootstrap modals. To achieve the same effect, use some custom JavaScript:

$('#myModal').on('shown.bs.modal', function () {

SCR37: Creating Custom Dialogs in a Device Independent Way


  • Be sure not to open a modal while another is still visible. Showing more than one modal at a time requires custom code.
  • Always try to place a modal's HTML code in a top-level position in your document to avoid other components affecting the modal's appearance and/or functionality.
  • There are some caveats regarding using modals on mobile devices. See Bootstrap's browser support docs for details.

Demo Modal

A rendered modal with header, body, and set of actions in the footer.

<!-- Button trigger modal -->
<button type="button" class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">
  Launch Demo Modal

<!-- Modal -->
<div id="myModal" class="modal fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
  <div class="modal-dialog" role="document">
    <div class="modal-content">

      <div class="modal-header">

        <h4 class="modal-title" id="myModalLabel">Modal title</h4>
      <div class="modal-body">

Usage Requires MAX Custom Bootstrap Stylesheet Requires MAX Custom Bootstrap JavaScript

The modal plugin toggles your hidden content on demand, via data attributes or JavaScript. It also adds .modal-open to the <body> to override default scrolling behavior and generates a .modal-backdrop to provide a click area for dismissing shown modals when clicking outside the modal.

Via Data Attributes

Activate a modal without writing JavaScript. Set data-toggle="modal" on a controller element, like a button, along with a data-target="#foo" or href="#foo" to target a specific modal to toggle.

<button type="button" data-toggle="modal" data-target="#myModal">Launch modal</button>

Via JavaScript

Call a modal with id myModal with a single line of JavaScript:



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

Name type default description
backdrop boolean or the string 'static' true Includes a modal-backdrop element. Alternatively, specify static for a backdrop which doesn't close the modal on click.
keyboard boolean true Closes the modal when escape key is pressed
show boolean true Shows the modal when initialized.
remote path false

This option is deprecated since v3.3.0 and will be removed in v4. We recommend instead using client-side templating or a data binding framework, or calling jQuery.load yourself.

If a remote URL is provided, content will be loaded one time via jQuery's load method and injected into the .modal-content div. If you're using the data-api, you may alternatively use the href attribute to specify the remote source. An example of this is shown below:

<a data-toggle="modal" href="remote.html"
data-target="#modal">Click me</a>



Activates your content as a modal. Accepts an optional options object.

  keyboard: false

Manually toggles a modal. Returns to the caller before the modal has actually been shown or hidden (i.e. before the shown.bs.modal or hidden.bs.modal event occurs).


Manually opens a modal. Returns to the caller before the modal has actually been shown (i.e. before the shown.bs.modal event occurs).


Manually hides a modal. Returns to the caller before the modal has actually been hidden (i.e. before the hidden.bs.modal event occurs).


Readjusts the modal's positioning to counter a scrollbar in case one should appear, which would make the modal jump to the left.

Only needed when the height of the modal changes while it is open.



Bootstrap's modal class exposes a few events for hooking into modal functionality.

All modal events are fired at the modal itself (i.e. at the <div class="modal">).

Event Type Description
show.bs.modal This event fires immediately when the show instance method is called. If caused by a click, the clicked element is available as the relatedTarget property of the event.
shown.bs.modal This event is fired when the modal has been made visible to the user (will wait for CSS transitions to complete). If caused by a click, the clicked element is available as the relatedTarget property of the event.
hide.bs.modal This event is fired immediately when the hide instance method has been called.
hidden.bs.modal This event is fired when the modal has finished being hidden from the user (will wait for CSS transitions to complete).
loaded.bs.modal This event is fired when the modal has loaded content using the remote option.
$('#myModal').on('hidden.bs.modal', function (e) {
  // do something...
