Where to find code for "Select with custom options"

@mikhailvolkov @volkdimitr

I want to modify the open-source code for the Business Forms plugin. Specifically, for the form element type “Select with custom options,” I want to display the current value of the element rather than the “Choose” that is displayed.

Currently I am looking within this directory: GitHub - VolkovLabs/business-forms at v4.9.0

Is there an existing feature that enables this? If not, do you know what file or folder I should look into to change this?

Thank you very much!
