At Webcon BPS, on the form's list of items, I have a checkbox field and a second field of dropdown(choose) type. The second filed - dropdown field retrieves data from a data base and allows for adding values outside of the database.
The first filed - checkbox field determines whether the value in the second field is from the source or added externally. How can changing the value of the checkbox field affect the behavior mode of the second dropdown(choose) field?
