This is a pre-use question. I am trying to figure out how best to set this up.
Lets say I want to have a For Sale Category. Below this would be 5 sub-categories, below each of these 5 sub-categories, would be 20 Sales Types (sub-sub-categories) which would be the same for all the 5 sub-categories, and below that would be 10 Price Ranges (sub-sub-sub categories) which would be the same for all the 20 Sales Types and on up to the 5 sub-categories.
What I envision happening for posting a sale would be to click on the For Sale Category, which then give you a choice of 5 sub-categories (hard coded), and whichever subcategory you choose you are then given a choice of 20 Sales Types sub-sub-categories (hard coded), and whichever Sales Type you chose you are given 10 Price Ranges (hard coded), which would bring you to the postings for ForSale>SubCat1>SalesType1>PriceRange1> (as an example). No posts would be allowed in any of the higher sub-categories until the user reaches this point. Where they can read and post messages, with a Title and body of text.
For reading messages, there could be 1 other option = All Price Ranges. This could also apply to ALL 5 sub-categories too by having an option to include all top level sub-categories by having an all choice too. But this would not be applicable for all Sales Types. Also, if any of these wildcards are chosen, it means readers cannot create new posts, but can read/post to the threads available. Which might be handled by a simple question "Have you got something to sell? When clicking on the For Sale Category. If Y you see the menu as explained above. if N you get the options All for both the sub-categories and the Price Ranges.
I’n not really familiar how tags really work, or if these could be added to the structure, if it would help. If they can be pre-defined.
If this suggestion is impractical. Are there any other suggestions which might achieve a similar result.
