Adding Triggers inside the state of a button

I'm attempting to add several triggers inside the state of a button , how can that be done ? 


Got a dropdown button

when you click it , it drops down a little menu , where you can select from 4 options

I want to trigger these 4 options to either trigger a new layer  , or a photo to appear. 

Tried a couple things , such as , adding triggers on top of the button , But the problem is that they are always there even with a variable added to them. Guessing you can't add a trigger to "enable" a hotspot when X happens ??

Thank you
