Here I got a list of countries in an autocomplete dropdown and trying to filter those by starting letters of the country name. Example: If we type "Aus" all the country name with "aus" are being filtered.(See screenshot). I want to filter only "Australia and Austria" or any other country names with starting letters "Aus".

How to do that?

My project structure looks like this:

I'm developing a React project in WebStorm, but I'm having a problem due to the structure I've set up.

Normally, WebStorm supports styled-components, autocomplete works fine, but the standard way to access the theme object I provide from ThemeProvider results in a very dirty piece of code.

To get cleaner code, I used an alternative way to send a function to styled-components and capture variables from the theme object as arguments, but that way WebStorm doesn't autocomplete.
