Not sure what you mean. Are you trying to show / hide the entire dropdowns for example2, 3 and 4, depending on the select in 1?

I wouldn't do that way, instead i would use cascading dropdown ( like in country - state - city ) by creating a main list ( with A,B,C ... ) and a second list with link to the first ( A-A1, A-A2, B-B1 ... and so on) and then use the dropdown for first list and a cascading drop down for second list while watching the linking element to the first list.
