How i can put a input selector opening to the top?

Hi,

i have a section with two containers.

  1. Container: has a 100vh where i want to have data to be scrollable
  2. Container: i stick it to the bottom with "Sticky 0 to bottom

now i want to add a selector in the 2) container but it always opens to the bottom and will undo the 100vh from the other container and make 1) container scrollable.

How i can make the selector input opening to the top?

Can we see a screenshot or a video? I’m not entirely sure what the problem is
