# Modal

Use Bootstrap's JavaScript modal plugin to add dialogs to your site for lightboxes, user notifications, or completely custom content.

## How it works

Before getting started with Bootstrap’s modal component, be sure to read the following as our menu options have recently changed.

- Modals are built with HTML, CSS, and JavaScript. They’re positioned over everything else in the document and remove scroll from the `<body>` so that modal content scrolls instead.
- Clicking on the modal “backdrop” will automatically close the modal.
- Bootstrap only supports one modal window at a time. Nested modals aren’t supported as we believe them to be poor user experiences.
- Modals use `position: fixed`, which can sometimes be a bit particular about its rendering. Whenever possible, place your modal HTML in a top-level position to avoid potential interference from other elements. You’ll likely run into issues when nesting a `.modal` within another fixed element.
- Once again, due to `position: fixed`, there are some caveats with using modals on mobile devices. See our browser support docs for details.
- Lastly, the `autofocus` HTML attribute has no effect in modals. Here’s how you can achieve the same effect with custom JavaScript.

Keep reading for demos and usage guidelines.

- 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 () {
      $('#myInput').focus()
    })

## Examples

### Modal components

Below is a static modal example (meaning its `position` and `display` have been overridden). Included are the modal header, modal body (required for `padding`), and modal footer (optional). We ask that you include modal headers with dismiss actions whenever possible, or provide another explicit dismiss action.

##### Modal title

Modal body text goes here.

    <div class="modal">
      <div class="modal-dialog" role="document">
        <div class="modal-content">
          <div class="modal-header">
            <h5 class="modal-title">Modal title</h5>
            <button type="button" class="close" data-dismiss="modal" aria-label="Close">
              <span aria-hidden="true">&times;</span>
            </button>
          </div>
          <div class="modal-body">
            <p>Modal body text goes here.</p>
          </div>
          <div class="modal-footer">
            <button type="button" class="btn btn-primary">Save changes</button>
            <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
          </div>
        </div>
      </div>
    </div>

### Live demo

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

##### Modal title

Woohoo, you're reading this text in a modal!

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

    <!-- Modal -->
    <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">
            <h5 class="modal-title" id="exampleModalLabel">Modal title</h5>
            <button type="button" class="close" data-dismiss="modal" aria-label="Close">
              <span aria-hidden="true">&times;</span>
            </button>
          </div>
          <div class="modal-body">
            ...
          </div>
          <div class="modal-footer">
            <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
            <button type="button" class="btn btn-primary">Save changes</button>
          </div>
        </div>
      </div>
    </div>

### Scrolling long content

When modals become too long for the user’s viewport or device, they scroll independent of the page itself. Try the demo below to see what we mean.

##### Modal title

      Launch demo modal
    </button>

    <!-- Modal -->
    <div class="modal fade" id="exampleModalLong" tabindex="-1" role="dialog" aria-labelledby="exampleModalLongTitle" aria-hidden="true">
      <div class="modal-dialog" role="document">
        <div class="modal-content">
          <div class="modal-header">

          </div>
          <div class="modal-footer">
            <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
            <button type="button" class="btn btn-primary">Save changes</button>
          </div>
        </div>
      </div>
    </div>

### Tooltips and popovers

Tooltips and popovers can be placed within modals as needed. When modals are closed, any tooltips and popovers within are also automatically dismissed.

##### Modal title

##### Popover in a modal

This button triggers a popover on click.

##### Tooltips in a modal

This link and that link have tooltips on hover.

    <div class="modal-body">
      <h5>Popover in a modal</h5>
      <p>This <a href="#" role="button" class="btn btn-secondary popover-test" title="Popover title" data-content="Popover body content is set in this attribute.">button</a> triggers a popover on click.</p>
      <hr>
      <h5>Tooltips in a modal</h5>
      <p><a href="#" class="tooltip-test" title="Tooltip">This link</a> and <a href="#" class="tooltip-test" title="Tooltip">that link</a> have tooltips on hover.</p>
    </div>

### Using the grid

Utilize the Bootstrap grid system within a modal by nesting `.container-fluid` within the `.modal-body`. Then, use the normal grid system classes as you would anywhere else.

##### Grids in modals

.col-md-4
.col-md-4 .ml-auto
.col-md-3 .ml-auto
.col-md-2 .ml-auto
.col-md-6 .ml-auto
Level 1: .col-sm-9
Level 2: .col-8 .col-sm-6
Level 2: .col-4 .col-sm-6

    <div class="modal-body">
      <div class="container-fluid">
        <div class="row">
          <div class="col-md-4">.col-md-4</div>
          <div class="col-md-4 ml-auto">.col-md-4 .ml-auto</div>
        </div>
        <div class="row">
          <div class="col-md-3 ml-auto">.col-md-3 .ml-auto</div>
          <div class="col-md-2 ml-auto">.col-md-2 .ml-auto</div>
        </div>
        <div class="row">
          <div class="col-md-6 ml-auto">.col-md-6 .ml-auto</div>
        </div>
        <div class="row">
          <div class="col-sm-9">
            Level 1: .col-sm-9
            <div class="row">
              <div class="col-8 col-sm-6">
                Level 2: .col-8 .col-sm-6
              </div>
              <div class="col-4 col-sm-6">
                Level 2: .col-4 .col-sm-6
              </div>
            </div>
          </div>
        </div>
      </div>
    </div>

### Varying modal content

Have a bunch of buttons that all trigger the same modal 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.

Below is a live demo followed by example HTML and JavaScript. For more information, read the modal events docs for details on `relatedTarget`.

##### New message

Recipient:
Message:

    <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">
            <h5 class="modal-title" id="exampleModalLabel">New message</h5>
            <button type="button" class="close" data-dismiss="modal" aria-label="Close">
              <span aria-hidden="true">&times;</span>
            </button>
          </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)
    })

### 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>

### Dynamic heights

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

### Accessibility

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`.

### 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 for more information.

## 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>

#### Large modal

...

#### Small modal

...

## 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=""`.

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
focus | boolean | true | Puts the focus on the modal when initialized.
show | boolean | true | Shows the modal when initialized.

### Methods

#### Asynchronous methods and transitions

All API methods are asynchronous and start a transition. They returns to the caller as soon as the transition is started but before it ends. In addition, a method call on a transitioning component will be ignored.

See our Javascript documentation for more informations.

#### `.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')

#### `.modal('handleUpdate')`

Manually readjust the modal’s position if the height of a modal changes while it is open (i.e. in case a scrollbar appears).

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

### 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">`).

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).

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