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 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.
The animation effect of this component is dependent on the prefers-reduced-motion media query. See the reduced motion section of our accessibility documentation.

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)
})
