You can group a collection of items using tags. Items can have multiple tags, therefore showing on several different pages.
For example, if you have items that have a backyard Luau them, simply tag them as “Backyard Luau” in Goodshuffle Pro.
You can then add in the code snippet to the page where you want to display your inventory by tags.
Now any items tagged “Backyard Luau” will display together.
