and see them play

1. Select the first button and on the Attributes section of the Design pane, define the target for the Data-toggle. Something like  mon-artist-1  would work. 

2. Go to the Inspector pane. There you find a hidden subgrid element below the last text-link. Click the eye to make it visible if you like. Double-clicking the element will take you to the Design pane where you give it an ID of  mon-artist-1  .

3. That’s all, everything should work. You can duplicate the element and update the targets, IDs and content for each of the buttons and pop ups. Animations can be changed with the Data-animate attribute.

4. If you want to close a pop-up when another button is clicked, simply add the IDs of the other pop-ups to the Data-close attribute of the respective buttons. You can see how this is done by looking at the Saturday and Sunday examples.
