Dropdown menu disappearing due to slider?

Question

css

Hello, dear intelligentsia. Initially, I made a simple drop-down menu when hovering over a block. As soon as I put the slider at the bottom, I had such a problem that when I hovered over the menu, it simply closed. I set the parent class to position: realative and the child class to position: absolute

Answer 1

now set the dropdown menu to z-index:100; or some other meaning
