Location input propositions are behind a list

Hello everyone,
I’m having a problem with my webapp, when I enter a location on the location input component, the differents localisation proposition are behind a List that i created just under ( example on the picture).
I already tried to arrange the position with “brign forward” and " send to the front" but it’s not working.
It works on the normal app but not on the webapp. If you have any idea how to solve this i would love to know it.
Thank you
