+description: Documentation and examples for adding custom Bootstrap tooltips with CSS and JavaScript using CSS3 for animations and data-attributes for local title storage.
+group: components
+toc: true

+
+## Overview
+
+Things to know when using the tooltip plugin:
+
+- Tooltips rely on the 3rd party library [Popper.js](https://popper.js.org) for positioning. You must include [popper.min.js](https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.9.9/umd/popper.min.js) before bootstrap.js in order for tooltips to work!
+- Tooltips are opt-in for performance reasons, so **you must initialize them yourself**.
+- Tooltips with zero-length titles are never displayed.
+- Specify `container: 'body'` to avoid rendering problems in more complex components (like our input groups, button groups, etc).
+- Triggering tooltips on hidden elements will not work.
+- Tooltips for `.disabled` or `disabled` elements must be triggered on a wrapper element.
+- When triggered from hyperlinks that span multiple lines, tooltips will be centered. Use `white-space: nowrap;` on your `<a>`s to avoid this behavior.
+- Tooltips must be hidden before their corresponding elements have been removed from the DOM.
+
+Got all that? Great, let's see how they work with some examples.
+
+## Example: Enable tooltips everywhere
+
+One way to initialize all tooltips on a page would be to select them by their `data-toggle` attribute:
+
+{% highlight js %}
+$(function () {
+  $('[data-toggle="tooltip"]').tooltip()
+})
+{% endhighlight %}
+
+## Examples
+
+Hover over the links below to see tooltips:
+
+<div class="bd-example tooltip-demo">
+  <p class="muted">Tight pants next level keffiyeh <a href="#" data-toggle="tooltip" title="Default tooltip">you probably</a> haven't heard of them. Photo booth beard raw denim letterpress vegan messenger bag stumptown.

+<button type="button" class="btn btn-secondary" data-toggle="tooltip" data-placement="left" title="Tooltip on left">
+  Tooltip on left
+</button>
+{% endhighlight %}
+
+And with custom HTML added:
+
+{% highlight html %}
+<button type="button" class="btn btn-secondary" data-toggle="tooltip" data-html="true" title="<em>Tooltip</em> <u>with</u> <b>HTML</b>">
+  Tooltip with HTML
+</button>
+{% endhighlight %}
+
+## Usage
+
+The tooltip plugin generates content and markup on demand, and by default places tooltips after their trigger element.
+
+Trigger the tooltip via JavaScript:
+
+{% highlight js %}
+$('#example').tooltip(options)
+{% endhighlight %}
+
+### Markup
+
+The required markup for a tooltip is only a `data` attribute and `title` on the HTML element you wish to have a tooltip. The generated markup of a tooltip is rather simple, though it does require a position (by default, set to `top` by the plugin).
+
+{% callout warning %}
+#### Making tooltips work for keyboard and assistive technology users
+
+You should only add tooltips to HTML elements that are traditionally keyboard-focusable and interactive (such as links or form controls). Although arbitrary HTML elements (such as `<span>`s) can be made focusable by adding the `tabindex="0"` attribute, this will add potentially annoying and confusing tab stops on non-interactive elements for keyboard users. In addition, most assistive technologies currently do not announce the tooltip in this situation.
+{% endcallout %}
+
+{% highlight html %}
+<!-- HTML to write -->
+<a href="#" data-toggle="tooltip" title="Some tooltip text!">Hover over me</a>
+
+<!-- Generated markup by the plugin -->
+<div class="tooltip bs-tooltip-top" role="tooltip">
+  <div class="arrow" x-arrow></div>
+  <div class="tooltip-inner">
+    Some tooltip text!
+  </div>
+</div>
+{% 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 table-responsive">
+  <thead>
+    <tr>

+#### Data attributes for individual tooltips
+
+Options for individual tooltips can alternatively be specified through the use of data attributes, as explained above.
+{% endcallout %}
+
+### Methods
+
+{% capture callout-include %}{% include callout-danger-async-methods.md %}{% endcapture %}
+{{ callout-include | markdownify }}
+
+#### `$().tooltip(options)`
+
+Attaches a tooltip handler to an element collection.
+
+#### `.tooltip('show')`
+
+Reveals an element's tooltip. **Returns to the caller before the tooltip has actually been shown** (i.e. before the `shown.bs.tooltip` event occurs). This is considered a "manual" triggering of the tooltip. Tooltips with zero-length titles are never displayed.
+
+{% highlight js %}$('#element').tooltip('show'){% endhighlight %}
+
+#### `.tooltip('hide')`
+
+Hides an element's tooltip. **Returns to the caller before the tooltip has actually been hidden** (i.e. before the `hidden.bs.tooltip` event occurs). This is considered a "manual" triggering of the tooltip.
+
+{% highlight js %}$('#element').tooltip('hide'){% endhighlight %}
+
+#### `.tooltip('toggle')`
+
+Toggles an element's tooltip. **Returns to the caller before the tooltip has actually been shown or hidden** (i.e. before the `shown.bs.tooltip` or `hidden.bs.tooltip` event occurs). This is considered a "manual" triggering of the tooltip.
+
+{% highlight js %}$('#element').tooltip('toggle'){% endhighlight %}
+
+#### `.tooltip('dispose')`
+
+Hides and destroys an element's tooltip. Tooltips that use delegation (which are created using [the `selector` option](#options)) cannot be individually destroyed on descendant trigger elements.
+
+{% highlight js %}$('#element').tooltip('dispose'){% endhighlight %}
+
+#### `.tooltip('enable')`
+
+Gives an element's tooltip the ability to be shown. **Tooltips are enabled by default.**
+
+{% highlight js %}$('#element').tooltip('enable'){% endhighlight %}
+
+#### `.tooltip('disable')`
+
+Removes the ability for an element's tooltip to be shown. The tooltip will only be able to be shown if it is re-enabled.
+
+{% highlight js %}$('#element').tooltip('disable'){% endhighlight %}
+
+#### `.tooltip('toggleEnabled')`
+
+Toggles the ability for an element's tooltip to be shown or hidden.
+
+{% highlight js %}$('#element').tooltip('toggleEnabled'){% endhighlight %}
+
+#### `.tooltip('update')`
+
+Updates the position of an element's tooltip.
+
+{% highlight js %}$('#element').tooltip('update'){% endhighlight %}
