React native multi select dropdown menu

Question

I am new in React native. Lots of syntax are new to me. I want to make custom animated Multi-select dropdown menu. It will help me better understanding the native's syntax. I don't know which react native elements I should use TextInput or flatlist for that. My goal is make multi select dropdown menu like this image.

PS: I don't want to use library for that. It will not help me to understand how the react native's elements and its props work.

I will be glad if someone help me out.

if you don't want use library, let's refer index.js or another of library, you can understand how the react native's elements and its props work. example
