Overview

Things to know when using the popover plugin:

• Popovers 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 popovers to work!
• Popovers require the tooltip plugin as a dependency.
• Popovers are opt-in for performance reasons, so you must initialize them yourself.
• Zero-length title and content values will never show a popover.
• Specify container: 'body' to avoid rendering problems in more complex components (like our input groups, button groups, etc).
• Triggering popovers on hidden elements will not work.
• Popovers for .disabled or 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 .text-nowrap on your <a>s 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: Enable popovers everywhere

One way to initialize all popovers on a page would be to select them by their data-toggle attribute:

var popoverTriggerList = [].slice.call(document.querySelectorAll('[data-bs-toggle="popover"]'))
var popoverList = popoverTriggerList.map(function (popoverTriggerEl) {
    return new bootstrap.Popover(popoverTriggerEl)
})

Example: Using the container option

When you have some styles on a parent element that interfere with a popover, you’ll want to specify a custom container so that the popover’s HTML appears within that element instead.

var popover = new bootstrap.Popover(document.querySelector('.example-popover'), {
container: 'body'
})

Example

<button type="button" class="btn btn-lg btn-danger" data-toggle="popover" title="Popover title" data-content="And here's some amazing content. It's very engaging. Right?">Click to toggle popover</button>

Four directions

<button type="button" class="btn btn-secondary" data-container="body" data-toggle="popover" data-placement="top" data-content="Vivamus sagittis lacus vel augue laoreet rutrum faucibus.">
    Popover on top
</button>

<button type="button" class="btn btn-secondary" data-container="body" data-toggle="popover" data-placement="right" data-content="Vivamus sagittis lacus vel augue laoreet rutrum faucibus.">
    Popover on right
</button>

<button type="button" class="btn btn-secondary" data-container="body" data-toggle="popover" data-placement="bottom" data-content="Vivamus sagittis lacus vel augue laoreet rutrum faucibus.">
    Popover on bottom
</button>

<button type="button" class="btn btn-secondary" data-container="body" data-toggle="popover" data-placement="left" data-content="Vivamus sagittis lacus vel augue laoreet rutrum faucibus.">
    Popover on left
</button>
