Adding a frame containing chord diagrams

I wish to create a box below the title into which chord diagrams will be placed. I believe what I want is called a vertical frame, but when I click "Add | Frame | Insert vertical frame" nothing happens. I don't know how to control where the frame is to be placed.

Also, I have a palette of fretboard diagrams, but can only seem to place them with a selected note, not within an existing frame, so as you can see I am missing some essential concepts.
