I have a perspective project that for various reasons I had to incorporate an onscreen keyboard built into the project itself as a popup. My issue arises when I try to incorporate a drop-down component. Usually, this component can filter its bound options with a regular keyboard, but again I cant use that. For the keyboard popup, it returns a typed in string and although i try to set the 'searchParam' property for the dropdown, it does not filter. I dont know if its because it loses focus between the keyboard and Dropdown but i could use some help figuring out if theres a way to filter a dropdown via scripting.
This method works on table filtering, but it doesn't seem to work on the drop down like you mentioned. It might be a bug.
