Demo App: Bigger drop-down and search functionality

[thetsajeet]

Currently, the screen size of the dropdown is small, and it's harder to find the right item.

I would like to suggest a bigger dropdown window perhaps with a search functionality on it to show the options based on keywords entered.

I could take up this issue if you find it worth implementing.

This is a good idea, thanks @TS-A!
