I think you'll have to create your own. You could probably do what you want this way (editing tooltip.js):
- add a delay between
mouseleave
and closing the popover to give you time to move your mouse to the popover - bind events to the popover element itself as well, so you track it's mouseenter/mouseleave
- keep a counter of elements inside, incremented on mouseenter and decremented on mouseleave. Only finally close the tooltip if the counter is 0 after the leave delay
