@ishan621 I noticed that the opening/closing of the dropdowns have a small animation. Could you check if we can remove that animation and make them open/close instantly?

Also, are we using the input itself as the search input for searching the dropdown? That shouldn't be the case. There should be a searchbar inside the dropdown (refer to the design here

And on opening a dropdown that has the searchbar, the focus should be on the searchbar by default so that the user can open it and start typing. But the input on clicking which the dropdown opens should not be a field where you type to search.

Refer to this file too

more notes are mentioned here
