Interactive Table

Hello,

I am building an interactive table, where if someone clicks on a specific action I comment on the action. I have added ten layers for the ten actions. I would like for the user to be able to return to the base level table after seeing my comments, but I have been unable to put a button on the bottom. I also tried and was unsuccessful at adding a lightbox whenever a user clicked on a hotbox. But I could not see where a lightbox could be used unless it was a Quiz. Suggestions?
