Does this mean i have to start over?

i made a cute little nav bar and am adding drop-downs to it. but i made each button on a separate layer so my labels and everything dont really correspond…therefore meaning my drop-downs dont work. i need to get all 4 of my buttons onto the same layer…is there anyway to do this without completely starting over?
also i dont know how to upload my file to put on here so people can actually see want in the world i’m attempting to do
