I want to display data in a grid form but still allow the user to add or delete items from it. I am not sure what control or approach I should do for this and need some help. I have attached a screenshot of what I am trying to mimic.
The first row (basic, basic plus, premium, etc) will always stay the same. But the rows that have a description might be added/extended (Listing, Until Sold Listing, Enhanced Listing, etc). So I want to allow the user to add an extra "feature" which adds to the rows (after MLS + Realtor.com). I also want to allow the user to check off what features each columns can have.
