title: Modal
group: components

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

## Contents

* Will be replaced with the ToC, excluding the "Contents" header
{:toc}

**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:

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

{% callout warning %}
#### 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.
{% endcallout %}

{% callout warning %}
#### 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.
{% endcallout %}

{% callout warning %}
#### Mobile device caveats

There are some caveats regarding using modals on mobile devices. [See our browser support docs](../getting-started/#support-fixed-position-keyboards) for details.

### Live demo

Toggle a modal via JavaScript by clicking the button below. It will slide down and fade in from the top of the page.

<div id="myModal" class="modal fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
  <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 aria-hidden="true">&times;</span>
          <span class="sr-only">Close</span>
        </button>
        <h4 class="modal-title" id="myModalLabel">Modal title</h4>
      </div>
      <div class="modal-body">
        <h4>Text in a modal</h4>
        <p>Duis mollis, est non commodo luctus, nisi erat porttitor ligula.</p>

        <h4>Popover in a modal</h4>
        <p>This <a href="javascript:;" role="button" class="btn btn-secondary popover-test" title="A Title" data-content="And here's some amazing content. It's very engaging. right?">button</a> should trigger a popover on click.</p>

        <h4>Tooltips in a modal</h4>
        <p><a href="javascript:;" class="tooltip-test" title="Tooltip">This link</a> and <a href="javascript:;" class="tooltip-test" title="Tooltip">that link</a> should have tooltips on hover.</p>

#### Make modals accessible

Be sure to add `role="dialog"` and `aria-labelledby="..."``, referencing the modal title, to `.modal`, and `role="document"` to the `.modal-dialog` itself.

Additionally, you may give a description of your modal dialog with `aria-describedby` on `.modal`.
{% endcallout %}

{% callout info %}
#### Embedding YouTube videos

Embedding YouTube videos in modals requires additional JavaScript not in Bootstrap to automatically stop playback and more. [See this helpful Stack Overflow post](http://stackoverflow.com/questions/18622508/bootstrap-3-and-youtube-in-modal) for more information.
{% endcallout %}

## Optional sizes

Modals have two optional sizes, available via modifier classes to be placed on a `.modal-dialog`.

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

{% highlight html %}
<!-- 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>
{% endhighlight %}

<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 class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-label="Close">
          <span aria-hidden="true">&times;</span>
          <span class="sr-only">Close</span>
        </button>
        <h4 class="modal-title" id="myLargeModalLabel">Large modal</h4>
      </div>
      <div class="modal-body">
        ...
      </div>
    </div>
  </div>
</div>

<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 class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-label="Close">
          <span aria-hidden="true">&times;</span>
          <span class="sr-only">Close</span>
        </button>
        <h4 class="modal-title" id="mySmallModalLabel">Small modal</h4>
      </div>
      <div class="modal-body">
        ...
      </div>
    </div>
  </div>
</div>

## Remove animation

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

{% highlight html %}
<div class="modal" tabindex="-1" role="dialog" aria-labelledby="" aria-hidden="true">
  ...
</div>
{% endhighlight %}

## Using the grid system

To take advantage of the Bootstrap grid system within a modal, just nest `.container-fluid within the `.modal-body` and then use the normal grid system classes within this container.

{% example html %}
<div id="gridSystemModal" class="modal fade" tabindex="-1" role="dialog" aria-labelledby="gridModalLabel" aria-hidden="true">
  <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 aria-hidden="true">&times;</span></button>
        <h4 class="modal-title" id="gridModalLabel">Modal title</h4>
      </div>
      <div class="modal-body">
        <div class="row">
          <div class="col-md-4">.col-md-4</div>
          <div class="col-md-4 col-md-offset-4">.col-md-4 .col-md-offset-4</div>
        </div>
        <div class="row">
          <div class="col-md-3 col-md-offset-3">.col-md-3 .col-md-offset-3</div>
          <div class="col-md-2 col-md-offset-4">.col-md-2 .col-md-offset-4</div>
        </div>
        <div class="row">
          <div class="col-md-6 col-md-offset-3">.col-md-6 .col-md-offset-3</div>
        </div>
        <div class="row">
          <div class="col-sm-9">
            Level 1: .col-sm-9
            <div class="row">
              <div class="col-xs-8 col-sm-6">
                Level 2: .col-xs-8 .col-sm-6
              </div>
              <div class="col-xs-4 col-sm-6">
                Level 2: .col-xs-4 .col-sm-6
              </div>
            </div>
          </div>
        </div>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Save changes</button>
      </div>
    </div>
  </div>
</div>
<div class="bd-example bd-example-padded-bottom">
  <button type="button" class="btn btn-primary btn-lg" data-toggle="modal" data-target="#gridSystemModal">
    Launch demo modal
  </button>
</div>
{% endexample %}

## 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](https://developer.mozilla.org/en-US/docs/Web/Guide/HTML/Using_data_attributes) (possibly [via jQuery](http://api.jquery.com/data/)) to vary the contents of the modal depending on which button was clicked. See the Modal Events docs for details on `relatedTarget`.

{% example html %}
<div class="bd-example">
  <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="close" data-dismiss="modal" aria-label="Close">
            <span aria-hidden="true">&times;</span>
            <span class="sr-only">Close</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="control-label">Recipient:</label>
              <input type="text" class="form-control" id="recipient-name">
            </div>
            <div class="form-group">
              <label for="message-text" class="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>
</div>
{% endexample %}

{% highlight js %}
$('#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)
})
{% endhighlight %}

## 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.

{% highlight html %}
<button type="button" data-toggle="modal" data-target="#myModal">Launch modal</button>
{% endhighlight %}

### Via JavaScript

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

{% highlight js %}$('#myModal').modal(options){% endhighlight %}

### Options

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

<div class="table-responsive">
  <table class="table table-bordered table-striped">
    <thead>
     <tr>
       <th style="width: 100px;">Name</th>
       <th style="width: 50px;">type</th>
       <th style="width: 50px;">default</th>
       <th>description</th>
     </tr>
    </thead>
    <tbody>
     <tr>
       <td>backdrop</td>
       <td>boolean or the string <code>'static'</code></td>
       <td>true</td>
       <td>Includes a modal-backdrop element. Alternatively, specify <code>static</code> for a backdrop which doesn't close the modal on click.</td>
     </tr>
     <tr>
       <td>keyboard</td>
       <td>boolean</td>
       <td>true</td>
       <td>Closes the modal when escape key is pressed</td>
     </tr>
     <tr>
       <td>show</td>
       <td>boolean</td>
       <td>true</td>
       <td>Shows the modal when initialized.</td>
     </tr>
    </tbody>
  </table>
</div>

### Methods

#### .modal(options)

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

{% highlight js %}
$('#myModal').modal({
  keyboard: false
})
{% endhighlight %}

#### .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).

{% highlight js %}$('#myModal').modal('toggle'){% endhighlight %}

#### .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).

{% highlight js %}$('#myModal').modal('show'){% endhighlight %}

#### .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).

{% highlight js %}$('#myModal').modal('hide'){% endhighlight %}

### 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">`).

<div class="table-responsive">
  <table class="table table-bordered table-striped">
    <thead>
     <tr>
       <th style="width: 150px;">Event Type</th>
       <th>Description</th>
     </tr>
    </thead>
    <tbody>
     <tr>
       <td>show.bs.modal</td>
       <td>This event fires immediately when the <code>show</code> instance method is called. If caused by a click, the clicked element is available as the <code>relatedTarget</code> property of the event.</td>
     </tr>
     <tr>
       <td>shown.bs.modal</td>
       <td>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 <code>relatedTarget</code> property of the event.</td>
     </tr>
     <tr>
       <td>hide.bs.modal</td>
       <td>This event is fired immediately when the <code>hide</code> instance method has been called.</td>
     </tr>
     <tr>
       <td>hidden.bs.modal</td>
       <td>This event is fired when the modal has finished being hidden from the user (will wait for CSS transitions to complete).</td>
     </tr>
     <tr>
       <td>loaded.bs.modal</td>
       <td>This event is fired when the modal has loaded content using the <code>remote</code> option.</td>
     </tr>
    </tbody>
  </table>
</div>

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