Please help me out as fast as possible, because tomorrow it is the deadline of a project I have at my job and I cannot finish it because I cannot find out the index of a selected value of a Select field.

In need the Select floor selected index so I can make a conditional statement in order to get in the Select room field only the rooms from that selected floor. But how to get it ?
Currently, I get all the rooms from all the floors since the data comes from a Nested Repeater like in this picture below:
See pic 2.png
The get_row_index needs to assign to a dynamic value that is the selected option from the Select Floor field.
