Overview
- Zero-length
title
andcontent
attributes will never show a popover. - Triggering popovers on hidden elements will not work.
- Popovers for
disabled
elements must be triggered on a wrapper element. - When triggered from anchors that wrap across multiple lines, popovers will be centered between the anchors' overall width. Use

on yourb-a
components to avoid this behavior. - Popovers must be hidden before their corresponding elements have been removed from the DOM.
- Popovers can be triggered thanks to an element inside a shadow DOM.
Example
Four directions
Four options are available: top, right, bottom, and left aligned. Directions are mirrored when using Bootstrap in RTL.
Dismiss on next click
Use the focus
trigger to dismiss popovers on the user's next click of a different element than the toggle element.
Disabled elements
Elements with the disabled
attribute aren't interactive, meaning users cannot hover or click them to trigger a popover (or tooltip). As a workaround, you'll want to trigger the popover from a wrapper b-div
component or span
tag, ideally made keyboard-focusable using tabindex="0"
.
For disabled popover triggers, you may also prefer trigger="hover focus"
so that the popover appears as immediate visual feedback to your users as they may not expect to _click_ on a disabled element.
