A friend of mine and I have been trying to figure out how to hide the project listing in the start, and have it appear soon as you click a category which is placed strategically in the 2nd column, the project listing would appear in 3rd column, and then the project description would appear in the 4th column, leaving the content area with only images with (previous | next) toggle to browse through the images accompanying the project.
Anyone could shed some light on how to make this achievable?
Here's an image sample of the menu structure, and overall site structure – IMAGE
Level 1 is permanently shown, level 2 + level 3 is entirely depedent on the user's clicks, etc.
