you wrap the link which you are clicking and the tooltip in a container and add a class to the container and add a class to the tooltip aswell and make sure to add the tooltip visibility :visible when you hover the container as well in the mean
and some properties as well related to width of tooltip with that you can hover on your tooltip as well;
or else go in a format of creation of your own tooltip where it is easy in the format of wrapping the tooltip data which you want to show in the hovering container itself and make the tooltip data to position:absolute and other properties aswell for placing your tooltip in a desired position.
hope this helps
Thanks for your answer. It is however not yet so clear to me what you mean in the first part. Could you explain a little further? I do not understand what you mean with .con .tool, can you explain? Creating my own tooltip is not feasible at this point. Thanks!
