A hyperlink with a Slicer?

Anonymous , I doubt the first one is possible. The best you can have it is on a table

I tried with hyper link in the slicer. It is the same as a normal slicer.

For the second one, they should filter , if there are from same table

Else you can follow the approach of adding a visual level filter of fact measure not blank.
