Search-as-you-type field

Hello Everyone,

I'm creating an interactive eLearning in Storyline that mimics some of the fields in a piece of software that we use. However, I'm having trouble replicating a search-as-you-type field (image included for reference) I've figured out how to make a regular dropdown but I would like to be able to have users search for entries in that dropdown.

I tried different layers and states triggered by key presses but the problem I ran into is that they have to click outside of the text entry box after every letter for the trigger to activate and this requires the user to type a specific word.

Has anyone had any type of success in replicating a search-as-you-type field? Any help is greatly appreciated.
