Can you conditionally show/hide individual dropdown options?

I see how to conditionally show/hide dropdowns as a whole, but is there a way to show/hide specific dropdown options? Would you just need to create dropdowns for each situation and show/hide them as necessary?

You cannot conditionally setup the options inside a regular Dropdown Field. What you can use as an alternative is a widget called Dynamic Dropdowns. It will allow you to create nested dropdowns.

e.g.

IF A THEN SHOW

A1

A2

A3

IF B THEN SHOW

B1

B2

B3

...and so on
