css drop-down menu

I am adding a drop-down menu to a website and controlling it through css. After clicking the navigation column on the homepage, the drop-down menu can be displayed normally and jump to the corresponding page, but in other column pages When clicking the navigation column, the drop-down menu is also displayed, but the displayed layer is below, so that when the mouse is pulled down, it cannot jump to the corresponding page. How to solve this situation?
