Microsoft Form Drop Down List Issue

Hi Jernyn_Ho from a usability perspective a dropdown with 3000 items would be a nightmare. If I had been asked to do this my immediate reaction would be to look at using a Power Apps form with cascading dropdowns.

A very simple example I produced linked to a SharePoint list was for a user to select a county in the UK and the following dropdown contained just those towns and villages in that county. So although the list of towns and villages was several thousand long, a user only ever saw a much smaller number relevant to the earlier selection.

So something along those lines would be my recommendation for achieving what you've been asked to do.
