Inspired by the excellent jQuery.tipsy plugin written by Jason Frame; Tooltips are an updated version, which don't rely on images, use CSS3 for animations, and data-attributes for local title storage.

Tooltips with zero-length titles are never displayed.

Examples

Hover over the links below to see tooltips:

Static tooltip

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

{% highlight html %} {% endhighlight %}

Opt-in functionality

For performance reasons, the Tooltip and Popover data-apis are opt-in, meaning you must initialize them yourself.

Tooltips in button groups and input groups require special setting

When using tooltips on elements within a .btn-group or an .input-group, you'll have to specify the option container: 'body' (documented below) to avoid unwanted side effects (such as the element growing wider and/or losing its rounded corners when the tooltip is triggered).

Don't try to show tooltips on hidden elements

Invoking $(...).tooltip('show') when the target element is display: none; will cause the tooltip to be incorrectly positioned.

Tooltips on disabled elements require wrapper elements

To add a tooltip to a disabled or .disabled element, put the element inside of a <div> and apply the tooltip to that <div> instead.

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).

Multiple-line links

Sometimes you want to add a tooltip to a hyperlink that wraps multiple lines. The default behavior of the tooltip plugin is to center it horizontally and vertically. Add white-space: nowrap; to your anchors to avoid this.

{% highlight html %} Hover over me {% endhighlight %}

Options

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

Name	Type	Default	Description
animation	boolean	true	Apply a CSS fade transition to the tooltip
container	string \| false	false	Appends the tooltip to a specific element. Example: `container: 'body'`. This option is particularly useful in that it allows you to position the tooltip in the flow of the document near the triggering element - which will prevent the tooltip from floating away from the triggering element during a window resize.
delay	number \| object	0	Delay showing and hiding the tooltip (ms) - does not apply to manual trigger type If a number is supplied, delay is applied to both hide/show Object structure is: `delay: { "show": 500, "hide": 100 }`
html	boolean	false	Insert HTML into the tooltip. If false, jQuery's `text` method will be used to insert content into the DOM. Use text if you're worried about XSS attacks.
placement	string \| function	'top'	How to position the tooltip - top \| bottom \| left \| right \| auto. When "auto" is specified, it will dynamically reorient the tooltip. For example, if placement is "auto left", the tooltip will display to the left when possible, otherwise it will display right. When a function is used to determine the placement, it is called with the tooltip DOM node as its first argument and the triggering element DOM node as its second. The `this` context is set to the tooltip instance.
selector	string	false	If a selector is provided, tooltip objects will be delegated to the specified targets. In practice, this is used to enable dynamic HTML content to have tooltips added. See this and an informative example.
template	string	`'<div class="tooltip" role="tooltip"><div class="tooltip-arrow"></div><div class="tooltip-inner"></div></div>'`	Base HTML to use when creating the tooltip. The tooltip's `title` will be injected into the `.tooltip-inner`. `.tooltip-arrow` will become the tooltip's arrow. The outermost wrapper element should have the `.tooltip` class.
title	string \| function	''	Default title value if `title` attribute isn't present. If a function is given, it will be called with its `this` reference set to the element that the tooltip is attached to.
trigger	string	'hover focus'	How tooltip is triggered - click \| hover \| focus \| manual. You may pass multiple triggers; separate them with a space.
viewport	string \| object	{ selector: 'body', padding: 0 }	Keeps the tooltip within the bounds of this element. Example: `viewport: '#viewport'` or `{ "selector": "#viewport", "padding": 0 }`

Data attributes for individual tooltips

Options for individual tooltips can alternatively be specified through the use of data attributes, as explained above.

Methods

$().tooltip(options)

Attaches a tooltip handler to an element collection.

.tooltip('show')

Reveals an element's tooltip. Tooltips with zero-length titles are never displayed.

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

.tooltip('hide')

Hides an element's tooltip.

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

.tooltip('toggle')

Toggles an element's tooltip.

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

.tooltip('destroy')

Hides and destroys an element's tooltip.

{% highlight js %}$('#element').tooltip('destroy'){% endhighlight %}

Events

Event Type	Description
show.bs.tooltip	This event fires immediately when the `show` instance method is called.
shown.bs.tooltip	This event is fired when the tooltip has been made visible to the user (will wait for CSS transitions to complete).
hide.bs.tooltip	This event is fired immediately when the `hide` instance method has been called.
hidden.bs.tooltip	This event is fired when the tooltip has finished being hidden from the user (will wait for CSS transitions to complete).

{% highlight js %} $('#myTooltip').on('hidden.bs.tooltip', function () { // do something… }) {% endhighlight %}
