Overview
Things to know when using the tooltip plugin:
- Tooltips rely on the 3rd party library Popper.js for positioning. You must include popper.min.js before bootstrap.js or use
bootstrap.bundle.min.js
/bootstrap.bundle.js
which contains Popper.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
ordisabled
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.

Example: Enable tooltips everywhere
One way to initialize all tooltips on a page would be to select them by their data-bs-toggle
attribute:
var tooltipTriggerList = [].slice.call(document.querySelectorAll('[data-bs-toggle="tooltip"]'))
var tooltipList = tooltipTriggerList.map(function (tooltipTriggerEl) {
return new bootstrap.Tooltip(tooltipTriggerEl)
})
