Material Design has rich tooltips which can also be persistent. As it's explained here, these tooltips:
- remain active even when leaving the target region
- can contain links
- only disappear once you interact with another UI element
- not triggered by hover, they are only triggered by clicking the parent element
I know there has been a wide practice of not including links inside the tooltip due to usability concerns. If you have ever used or considered using them, what do you think are the usability risks of these?
My specific use case is using these persistent tooltips to show a link in them: 1- User is viewing a graph showing employee payroll. 2- When they click on a specific employee on the graph, they can see the name, lastname, phone number of the employee and a link in a tooltip. 3-The link would take the user to the employee details page.
