Popovers can contain any arbitrary HTML, Angular bindings and even directives! Simply enclose desired
content in
a <template> element.
You can easily override open and close triggers by specifying event names (separated by :) in
the
triggers property.
Alternatively you can take full manual control over popover opening / closing events.
Set the container property to "body" to have the popover be appended to the body instead of
the triggering
element's parent. This option is useful if the element triggering the popover is inside an element that
clips
its contents (i.e. overflow: hidden).
You can optionally pass in a context when manually triggering a popover.
Popover is currently: {{ popover.isOpen() ? 'open' : 'closed' }}
