Ok, So I need help on how to do this..
Imagine you had a building game and in a stat panel you had buildable obj's you could double click and place. Now I imagine that if you had alot of items you could build it would get disorganized. So can someone show me how to make it so that all the Walls have a category you can click and it shows all the walls you can build, or a category like floors were you can click it and it shows the floors you can place. I already know how to make the buildables but I need help organizing them into categories.
