Static tooltip
Four options are available: top, right, bottom, and left aligned.
Four directions
<button type="button" class="btn btn-default" data-toggle="tooltip" data-placement="left" title="Tooltip on left">Tooltip on left</button>
<button type="button" class="btn btn-default" data-toggle="tooltip" data-placement="top" title="Tooltip on top">Tooltip on top</button>
<button type="button" class="btn btn-default" data-toggle="tooltip" data-placement="bottom" title="Tooltip on bottom">Tooltip on bottom</button>
<button type="button" class="btn btn-default" data-toggle="tooltip" data-placement="right" title="Tooltip on right">Tooltip on right</button>Opt-in functionality
For performance reasons, the Tooltip and Popover data-apis are opt-in, meaning you must initialize them yourself.
One way to initialize all tooltips on a page would be to select them by their data-toggle attribute:
$(function () {
$('[data-toggle="tooltip"]').tooltip()
})Usage
The tooltip plugin generates content and markup on demand, and by default places tooltips after their trigger element.
Trigger the tooltip via JavaScript:
$('#example').tooltip(options)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).
<!-- HTML to write -->
<a href="#" data-toggle="tooltip" title="Some tooltip text!">Hover over me</a>
<!-- Generated markup by the plugin -->
<div class="tooltip top" role="tooltip">
<div class="tooltip-arrow"></div>
<div class="tooltip-inner">
Some tooltip text!
</div>
</div>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.
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).
Accessible tooltips for keyboard and assistive technology users
For users navigating with a keyboard, and in particular users of assistive technologies, you should only add tooltips to keyboard-focusable elements such as links, form controls, or any arbitrary element with a tabindex="0" attribute.
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.
Options
Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as in data-animation="".

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. 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.
$('#element').tooltip('show').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.
$('#element').tooltip('hide').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.
$('#element').tooltip('toggle').tooltip('destroy')
Hides and destroys an element's tooltip. Tooltips that use delegation (which are created using the selector option) cannot be individually destroyed on descendant trigger elements.
$('#element').tooltip('destroy')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). |
| inserted.bs.tooltip | This event is fired after the show.bs.tooltip event when the tooltip template has been added to the DOM. |
$('#myTooltip').on('hidden.bs.tooltip', function () {
// do something…
})
