Components.Popover public

Component that implements Bootstrap popovers.

By default, it will attach its listeners (click) to the parent DOM element to trigger the popover:

<button class="btn">
  <BsPopover @title="this is a title">and this the body</BsPopover>
</button>

Trigger

The trigger element is the DOM element that will cause the popover to be shown when one of the trigger events occur on that element. By default, the trigger element is the parent DOM element of the component, and the trigger event will be "click".

The triggerElement property accepts any CSS selector to attach the popover to any other existing DOM element.

To customize the events that will trigger the popover use the triggerEvents property, that accepts an array or a string of events, with "hover", "focus" and "click" being supported.

Placement options

By default, the popover will show up to the right of the trigger element. Use the placement property to change that ("top", "bottom", "left" and "right"). To make sure the popover will not exceed the viewport (see Advanced customization) you can set autoPlacement to true. A popover with `placement="right" will be placed to the right if there is enough space, otherwise to the left.

Advanced customization

Several other properties allow for some advanced customization:

• visible to show/hide the popover programmatically
• fade to disable the fade in transition
• delay (or delayShow and delayHide) to add a delay
• viewportSelector and viewportPadding to customize the viewport that affects autoPlacement
• a close action is yielded, that allows you to close the tooltip:

<BsPopover as |po| >This is a popover <button onclick={{action po.close}}>Close</button></BsPopover>

See the individual API docs for each property.

Actions

When you want to react on the popover being shown or hidden, you can use one of the following supported actions:

• onShow
• onShown
• onHide
• onHidden

Note that only invoking the component in a template as shown above is considered part of its public API. Extending from it (subclassing) is generally not supported, and may break at any time.
