I have 10 building, every building have more than 15 flates. for each flat I have one enumeration value. .In data view for selecting one value every time I need to scroll the whole page and list to find and select. Instead of a long list view I want to have an expandable list view, such as when i click dropdown button it show me 10 building names, when I click on name of one building it should expand and i can see the name of flates in that specific building. is that possible? any microflow, entity clue?

I would suggest using reference selectors and changing your domain model to something like:
Entity - Building (with name string attribute)
Entity - Flat (with name string attribute)
Association - One Building to Many flats
Once you create the right buildings and flats and associate them to each other you should be able to navigate through the flats in a building.
