❔ Distance dropdown list from combobox

Hello everyone, i designed a larger combobox using margin and padding, but the dropdown list appears where the non-styled combobox should be. I'm struggling to find the property to modify this value, could someone please help me? Edit: To be more clear, the selection box should be lower to let the above text be readable and expecially avoid conflicts between click down event on combo and click up on item to select it (which is the bigger problem right now)
