I wish to display a message according to dropdown selection

I would like a user to select from a drop down list and when a specific option is selected a description pops up but only for that selection. How can I do this with the nested drop down options?

I believe it is possible by adding Text fields with the different descriptions and then adding conditional logic so that it shows the message according to the selection:
