## Overview

Things to know when using the popover plugin:

- Popovers rely on the 3rd party library [Popper.js](https://popper.js.org/) for positioning. You must include [popper.min.js]({{ site.cdn.popper }}) before bootstrap.js or use `bootstrap.bundle.min.js` / `bootstrap.bundle.js` which contains Popper.js in order for popovers to work!
- Popovers require the [tooltip plugin]({{ site.baseurl }}/docs/{{ site.docs_version }}/components/tooltips/) as a dependency.
- If you're building our JavaScript from source, it [requires `util.js`]({{ site.baseurl }}/docs/{{ site.docs_version }}/getting-started/javascript/#util).
- Popovers are opt-in for performance reasons, so **you must initialize them yourself**.
- Zero-length `title` and `content` values will never show a popover.
- Specify `container: 'body'` to avoid rendering problems in more complex components (like our input groups, button groups, etc).
- Triggering popovers on hidden elements will not work.
- Popovers for `.disabled` or `disabled` elements must be triggered on a wrapper element.
- When triggered from anchors that wrap across multiple lines, popovers will be centered between the anchors' overall width. Use `.text-nowrap` on your `<a>`s to avoid this behavior.
- Popovers must be hidden before their corresponding elements have been removed from the DOM.

Keep reading to see how popovers work with some examples.

## Example: Enable popovers everywhere

One way to initialize all popovers on a page would be to select them by their `data-toggle` attribute:

{% highlight js %}
$(function () {
  $('[data-toggle="popover"]').popover()
})
{% endhighlight %}

## Example: Using the `container` option

When you have some styles on a parent element that interfere with a popover, you'll want to specify a custom `container` so that the popover's HTML appears within that element instead.

{% highlight js %}
$(function () {
  $('.example-popover').popover({
    container: 'body'
  })
})
{% endhighlight %}

## Example

{% capture example %}
<button type="button" class="btn btn-lg btn-danger" data-toggle="popover" title="Popover title" data-content="And here's some amazing content. It's very engaging. Right?">Click to toggle popover</button>
{% endcapture %}
{% include example.html content=example %}

### Four directions

Four options are available: top, right, bottom, and left aligned.

<div class="bd-example popover-demo">
  <div class="bd-example-popovers">
    <button type="button" class="btn btn-secondary" data-container="body" data-toggle="popover" data-placement="top" data-content="Vivamus sagittis lacus vel augue laoreet rutrum faucibus.">
      Popover on top
    </button>
    <button type="button" class="btn btn-secondary" data-container="body" data-toggle="popover" data-placement="right" data-content="Vivamus sagittis lacus vel augue laoreet rutrum faucibus.">
      Popover on right
    </button>
    <button type="button" class="btn btn-secondary" data-container="body" data-toggle="popover" data-placement="bottom" data-content="Vivamus sagittis lacus vel augue laoreet rutrum faucibus.">
      Popover on bottom
    </button>
    <button type="button" class="btn btn-secondary" data-container="body" data-toggle="popover" data-placement="left" data-content="Vivamus sagittis lacus vel augue laoreet rutrum faucibus.">
      Popover on left
    </button>
  </div>
</div>

{% highlight html %}
<button type="button" class="btn btn-secondary" data-container="body" data-toggle="popover" data-placement="top" data-content="Vivamus sagittis lacus vel augue laoreet rutrum faucibus.">
  Popover on top
</button>

<button type="button" class="btn btn-secondary" data-container="body" data-toggle="popover" data-placement="right" data-content="Vivamus sagittis lacus vel augue laoreet rutrum faucibus.">
  Popover on right
</button>

<button type="button" class="btn btn-secondary" data-container="body" data-toggle="popover" data-placement="bottom" data-content="Vivamus
sagittis lacus vel augue laoreet rutrum faucibus.">
  Popover on bottom
</button>

<button type="button" class="btn btn-secondary" data-container="body" data-toggle="popover" data-placement="left" data-content="Vivamus sagittis lacus vel augue laoreet rutrum faucibus.">
  Popover on left
</button>
{% endhighlight %}

### Dismiss on next click

Use the `focus` trigger to dismiss popovers on the user's next click of a different element than the toggle element.

{% capture callout %}
#### Specific markup required for dismiss-on-next-click

For proper cross-browser and cross-platform behavior, you must use the `<a>` tag, _not_ the `<button>` tag, and you also must include a [`tabindex`](https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/tabindex) attribute.
{% endcapture %}
{% include callout.html content=callout type="danger" %}

{% capture example %}
<a tabindex="0" class="btn btn-lg btn-danger" role="button" data-toggle="popover" data-trigger="focus" title="Dismissible popover" data-content="And here's some amazing content. It's very engaging. Right?">Dismissible popover</a>
{% endcapture %}
{% include example.html content=example %}

{% highlight js %}
$('.popover-dismiss').popover({
  trigger: 'focus'
})
{% endhighlight %}

### Disabled elements

Elements with the `disabled` attribute aren't interactive, meaning users cannot hover or click them to trigger a popover (or tooltip). As a workaround, you'll want to trigger the popover from a wrapper `<div>` or `<span>` and override the `pointer-events` on the disabled element.

For disabled popover triggers, you may also prefer `data-trigger="hover"` so that the popover appears as immediate visual feedback to your users as they may not expect to _click_ on a disabled element.

{% capture example %}
<span class="d-inline-block" data-toggle="popover" data-content="Disabled popover">
  <button class="btn btn-primary" style="pointer-events: none;" type="button" disabled>Disabled button</button>
</span>
{% endcapture %}
{% include example.html content=example %}

## Usage

Enable popovers via JavaScript:

{% highlight js %}$('#example').popover(options){% endhighlight %}

### Options

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

<table class="table table-bordered table-striped">
  <thead>
    <tr>
      <th style="width: 100px;">Name</th>
      <th style="width: 100px;">Type</th>

#### Data attributes for individual popovers

Options for individual popovers can alternatively be specified through the use of data attributes, as explained above.
{% endcapture %}
{% include callout.html content=callout type="info" %}

### Methods

{% include callout-danger-async-methods.md %}

#### `$().popover(options)`

Initializes popovers for an element collection.

#### `.popover('show')`

Reveals an element's popover. **Returns to the caller before the popover has actually been shown** (i.e. before the `shown.bs.popover` event occurs). This is considered a "manual" triggering of the popover. Popovers whose both title and content are zero-length are never displayed.

{% highlight js %}$('#element').popover('show'){% endhighlight %}

#### `.popover('hide')`

Hides an element's popover. **Returns to the caller before the popover has actually been hidden** (i.e. before the `hidden.bs.popover` event occurs). This is considered a "manual" triggering of the popover.

{% highlight js %}$('#element').popover('hide'){% endhighlight %}

#### `.popover('toggle')`

Toggles an element's popover. **Returns to the caller before the popover has actually been shown or hidden** (i.e. before the `shown.bs.popover` or `hidden.bs.popover` event occurs). This is considered a "manual" triggering of the popover.

{% highlight js %}$('#element').popover('toggle'){% endhighlight %}

#### `.popover('dispose')`

Hides and destroys an element's popover. Popovers that use delegation (which are created using [the `selector` option](#options)) cannot be individually destroyed on descendant trigger elements.

{% highlight js %}$('#element').popover('dispose'){% endhighlight %}

#### `.popover('enable')`

Gives an element's popover the ability to be shown. **Popovers are enabled by default.**

{% highlight js %}$('#element').popover('enable'){% endhighlight %}

#### `.popover('disable')`

Removes the ability for an element's popover to be shown. The popover will only be able to be shown if it is re-enabled.

{% highlight js %}$('#element').popover('disable'){% endhighlight %}

#### `.popover('toggleEnabled')`

Toggles the ability for an element's popover to be shown or hidden.

{% highlight js %}$('#element').popover('toggleEnabled'){% endhighlight %}

#### `.popover('update')`

Updates the position of an element's popover.

{% highlight js %}$('#element').popover('update'){% endhighlight %}
