Add Typing feature in dropdown in navbar

**Is your feature request related to a problem? Please describe.**
In the home-page we can search but we can not write in the input field
So when the user want to change the country name he may find some difficulty to change because he dont know whether he is typing correctly ?? or what he is typing

**Describe the solution you'd like**
We can add a texting feature inside the dropdown container so that the users can easily type and search

**Describe alternatives you've considered**

**Additional context**
