The Problem of this is, that I first have to scroll down the list so I can place the panel on top. The second problem is, that if the user scrolls up and accidentally scrolls up too much, the list will be reloaded directly because the panel has already been placed in 1st place.
I tried to place the panel only when a certain "offset" is reached, but this does not look good. And this is only works on IOS, because there i have offset in the negative area, because I can push the list there slowly down, but on Android I do not have, there comes the shadow, but no offset in the minus area.
