You must include [popper.min.js]({{< param "cdn.popper" >}}) before bootstrap.js or use `bootstrap.bundle.min.js` / `bootstrap.bundle.js` which contains Popper 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. -- Tooltips can be triggered thanks to an element inside a shadow DOM. - -{{< callout info >}} -{{< partial "callout-info-sanitizer.md" >}} -{{< /callout >}} - -{{< callout info >}} -{{< partial "callout-info-prefersreducedmotion.md" >}} -{{< /callout >}} - -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-bs-toggle` attribute: - -```js -var tooltipTriggerList = [].slice.call(document.querySelectorAll('[data-bs-toggle="tooltip"]')) -var tooltipList = tooltipTriggerList.map(function (tooltipTriggerEl) { - return new bootstrap.Tooltip(tooltipTriggerEl) -}) -``` - -## Examples - -Hover over the links below to see tooltips: - -<div class="bd-example tooltip-demo"> - <p class="muted">Placeholder text to demonstrate some <a href="#" data-bs-toggle="tooltip" title="Default tooltip">inline links</a> with tooltips. This is now just filler, no killer. Content placed here just to mimic the presence of <a href="#" data-bs-toggle="tooltip" title="Another tooltip">real text</a>. And all that just to give you an idea of how tooltips would look when used in real-world situations. So hopefully you've now seen how <a href="#" data-bs-toggle="tooltip" title="Another one here too">these tooltips on links</a> can work in practice, once you use them on <a href="#" data-bs-toggle="tooltip" title="The last tip!">your own</a> site or project. - </p> -</div> - -Hover over the buttons below to see the four tooltips directions: top, right, bottom, and left.

To resolve this, set the [`boundary` option](https://popper.js.org/docs/v2/modifiers/flip/#boundary) (for the flip modifier using the `popperConfig` option) to any HTMLElement to override the default value, `'clippingParents'`, such as `document.body`: - -```js -var exampleEl = document.getElementById('example') -var tooltip = new bootstrap.Tooltip(exampleEl, { - boundary: document.body // or document.querySelector('#boundary') -}) -``` -{{< /callout >}} - -### 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, and most assistive technologies currently do not announce the tooltip in this situation. Additionally, do not rely solely on `hover` as the trigger for your tooltip, as this will make your tooltips impossible to trigger for keyboard users. -{{< /callout >}} - -```html -<!-- HTML to write --> -<a href="#" data-bs-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="tooltip-arrow"></div> - <div class="tooltip-inner"> - Some tooltip text! - </div> -</div> -``` - -### Disabled elements - -Elements with the `disabled` attribute aren't interactive, meaning users cannot focus, hover, or click them to trigger a tooltip (or popover). As a workaround, you'll want to trigger the tooltip from a wrapper `<div>` or `<span>`, ideally made keyboard-focusable using `tabindex="0"`. - -<div class="tooltip-demo"> -{{< example >}} -<span class="d-inline-block" tabindex="0" data-bs-toggle="tooltip" title="Disabled tooltip"> - <button class="btn btn-primary" type="button" disabled>Disabled button</button> -</span> -{{< /example >}} -</div> - -### Options - -Options can be passed via data attributes or JavaScript. For data attributes, append the option name to `data-bs-`, as in `data-bs-animation=""`. Make sure to change the case type of the option name from camelCase to kebab-case when passing the options via data attributes. For example, instead of using `data-bs-customClass="beautifier"`, use `data-bs-custom-class="beautifier"`. - -{{< callout warning >}} -Note that for security reasons the `sanitize`, `sanitizeFn`, and `allowList` options cannot be supplied using data attributes. -{{< /callout >}} - -<table class="table"> - <thead> - <tr> - <th style="width: 100px;">Name</th> - <th style="width: 100px;">Type</th> - <th style="width: 50px;">Default</th> - <th>Description</th> - </tr> - </thead> - <tbody> - <tr> - <td><code>animation</code></td> - <td>boolean</td> - <td><code>true</code></td> - <td>Apply a CSS fade transition to the tooltip</td> - </tr> - <tr> - <td><code>container</code></td> - <td>string | element | false</td> - <td><code>false</code></td> - <td> - <p>Appends the tooltip to a specific element.
