Components.Popover Class
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">
{{#bs-popover title="This is a title"}}and this the body{{/bs-popover}}
</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 jQuery selector to attach the popover to any other existing DOM element.
With the special value "parentView" you can attach the popover to the DOM element of the parent component:
{{#my-component}}
{{#bs-popover triggerElement="parentView"}}This is a popover{{/bs-popover}}
{{/my-component}}
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:
visibleto show/hide the popover programmaticallyfadeto disable the fade in transitiondelay(ordelayShowanddelayHide) to add a delayviewportSelectorandviewportPaddingto customize the viewport that affectsautoPlacement
See the individual API docs for each property.
