How can I get a dropdown like this?

I wanted to get a dropdown like this that I show in this screenshot:https://postimg.cc/TpSMbPNK
So when you select an item, the list of zones is displayed below. In the capture, the Muros-Noia area is selected. I have tried with a spinner but the layout is not like the one shown in the screenshot. All the best.

That is really common for all smartphones, oh you do not mean a notification area?
