问题
I have a HTML-View and need position: relative;for placing some elements.
Then, i have a popover.
PROBLEM: Since some elements are positioned relative, z-index is not working anymore, and i found no way that the popover can overlap the relative positioned elements.
QUESTION how to make popovers working properly and using underlaying elements, which are positioned relative?
i gave the popover position: absolute; and then a second wrapper inside, with position: relative; and set them to a higher z-index (1000, e.g.).
how to use z-index with relative positioning?
