I asked how it helps with z-indexes not XY?

Also drop downs are "attached" to some element in the UI, and you probably want those menus to scroll with the page

"position: fixed" puts an element in a new stacking context, freeing it from the z-index of its parents.

The person you were responding to said they use "position: fixed" so they don't have to worry about z-indexes, and I was explaining why that works. See sibling reply for the more technical explanation.
