I am in the process of revamping and redesigning one of our more complex forms. Need to figure out if the user makes a specific selection, the following question becomes a required field.
Example:

If the user selects one of the 3 options marked with an arrow, the OTHER (EXPLAIN) free-entry section becomes required before moving on to the next page. However, if they select reconnect, the OTHER section doesnt become required. Also, Is there a way that IF they select one of those options, that field could go from minimized to automatically maximize indicating the user needs to fill it out.
Yes, multiple step multi-question problem I'm working on.
Appreciate any feedback or assistance.
