Modal

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

Modal full size

<!-- button -->
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#fullsizeModal">
  Launch demo modal
</button>

<!-- modal -->
<div id="fullsizeModal" class="modal fullsize-modal fade" role="dialog" data-backdrop="false">
  <button type="button" class="btn-close m-2 m-lg-4" data-dismiss="modal" aria-label="Close">
    <span class="icon icon-close icon-3x"></span>
    <span class="btn-close-label hidden-sm-down">esc</span>
  </button>
  <div class="modal-dialog modal-lg pt-3 py-md-5">
    <div class="modal-header">
      <h1 class="modal-title">Modal title</h1>
    </div>
    <div class="modal-body">
      <p>Cras mattis consectetur purus sit amet fermentum. Cras justo odio, dapibus ac facilisis in, egestas eget quam. Morbi leo risus, porta ac consectetur ac, vestibulum at eros. Cras justo odio, dapibus ac facilisis in, egestas eget quam. Morbi leo risus, porta ac consectetur ac, vestibulum at eros. Duis mollis, est non commodo luctus, nisi erat porttitor ligula.</p>
    </div>
    <div class="modal-footer">
      <input type="submit" class="btn btn-primary btn-block btn-lg" value="Adicionar" />
    </div>
  </div>
</div>

Static example

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

<div class="modal fade">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-label="Close">
          <span class="icon icon-close"></span>
        </button>
        <h4 class="modal-title">Modal title</h4>
      </div>
      <div class="modal-body">
        <p>Duis mollis, est non commodo luctus, nisi erat porttitor ligula.</p> 
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-primary mr-1" data-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Save changes</button>
      </div>
    </div><!-- /.modal-content -->
  </div><!-- /.modal-dialog -->
</div><!-- /.modal -->

HTML5 semantic

Use the custom JavaScript:

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

Multiple open modals not supported

Be sure not to open a modal while another is still visible. Showing more than one modal at a time requires custom code.

Modal markup placement

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.

Optional sizes

Modals have two optional sizes, available via modifier classes to be placed on a .modal-dialog. These sizes kick in at certain breakpoints to avoid horizontal scrollbars on narrower viewports.

<!-- Large modal -->
<button class="btn btn-primary" data-toggle="modal" data-target=".bd-example-modal-lg">Large modal</button>

<div class="modal fade bd-example-modal-lg" tabindex="-1" role="dialog" aria-labelledby="myLargeModalLabel" aria-hidden="true">
  <div class="modal-dialog modal-lg">
    <div class="modal-content">
      ...
    </div>
  </div>
</div>

<!-- Small modal -->
<button type="button" class="btn btn-primary" data-toggle="modal" data-target=".bd-example-modal-sm">Small modal</button>

<div class="modal fade bd-example-modal-sm" tabindex="-1" role="dialog" aria-labelledby="mySmallModalLabel" aria-hidden="true">
  <div class="modal-dialog modal-sm">
    <div class="modal-content">
      ...
    </div>
  </div>
</div>

Remove animation

For modals that simply appear rather than fade in to view, remove the .fade class from your modal markup.

<div class="modal" tabindex="-1" role="dialog" aria-labelledby="..." aria-hidden="true">
  ...
</div>

Varying modal content based on trigger button

Have a bunch of buttons that all trigger the same modal, just with slightly different contents? Use event.relatedTarget and HTML data-* attributes (possibly via jQuery) to vary the contents of the modal depending on which button was clicked. See the Modal Events docs for details on relatedTarget.

<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal" data-whatever="@mdo">Open modal for @mdo</button>
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal" data-whatever="@fat">Open modal for @fat</button>
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal" data-whatever="@getbootstrap">Open modal for @getbootstrap</button>
<div class="modal fade" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="btn-close" data-dismiss="modal" aria-label="Close">
          <span class="icon icon-close icon-2x"></span>
          <span class="btn-close-label hidden-sm-down">esc</span>
        </button>
        <h4 class="modal-title" id="exampleModalLabel">New message</h4>
      </div>
      <div class="modal-body">
        <form>
          <div class="form-group">
            <label for="recipient-name" class="form-control-label">Recipient:</label>
            <input type="text" class="form-control" id="recipient-name">
          </div>
          <div class="form-group">
            <label for="message-text" class="form-control-label">Message:</label>
            <textarea class="form-control" id="message-text"></textarea>
          </div>
        </form>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Send message</button>
      </div>
    </div>
  </div>
</div>

$('#exampleModal').on('show.bs.modal', function (event) {
  var button = $(event.relatedTarget) // Button that triggered the modal
  var recipient = button.data('whatever') // Extract info from data-* attributes
  // If necessary, you could initiate an AJAX request here (and then do the updating in a callback).
  // Update the modal's content. We'll use jQuery here, but you could use a data binding library or other methods instead.
  var modal = $(this)
  modal.find('.modal-title').text('New message to ' + recipient)
  modal.find('.modal-body input').val(recipient)
})

Modals with dynamic heights

If the height of a modal changes while it is open, you should call $('#myModal').data('bs.modal').handleUpdate() to readjust the modal’s position in case a scrollbar appears.

Usage

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:

$('#myModal').modal(options)

Options

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

Methods

.modal(options)

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

$('#myModal').modal({
  keyboard: false
})

.modal('toggle')

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).

$('#myModal').modal('toggle')

.modal('show')

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

$('#myModal').modal('show')

.modal('hide')

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

$('#myModal').modal('hide')

Events

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">).

$('#myModal').on('hidden.bs.modal', function (e) {
  // do something...
})
