In my angular project I have just updated material from 14 to 15. Now I have a problem with the css of ng2-tel-input. When I open the dropdown it seems under other material stuff and not on top like before upgrade (the library is no longer updated so I can't ask to the creators).
I already tried with z-index, position etc but nothing worked, the problem affects only material components.
If you suggest me something I would be grateful.
