Drop Down List Filter Question

Hmmm.... that is true the person who came up with slicers is a genius but, you are the genius who provided me with this genius idea and solution to a problem I couldn't find on my own so I thank you again from the bottom of my heart.

Also another question for you Lorenzo is there a way to hide and unhide certain columns using what is selected from a slicer. Like I pick Janitorial/disposable items from the category Slicer list and what it shows in the table is everything but Date Purchased and Date Expiration column. However if I pick snacks/grocery from the category slicer list it will show all columns including the Date purchased and Date expiration. The same goes with vendor Slicer If I select Costco It will show all columns including the Date purchased and Date expiration and if I select Staples the Date purchased and Date expiration column gets hidden. Hopefully this makes sense. Is there a way to use like a conditional format hide/unhide certain columns in a table based on a selection made in a slicer and still have the table editable? I'm just wondering. If it isn't possible, well that's life hehe
