expo – Dropdown picker in sectionList react-native

I try to render a dropdown-picker (react-native-dropdownpicker) in a sectionlist but it’s impossable to scroll the content of the dropdown. It only shows the first results.

I tried many things with zIndex, view with flex: 1 as parent but im unable to find the solution.

Is it possible to render in a sectionlist or should i be looking for another solution?
