A Query and Dropdown Menu Select

Knowledge Base: It has unlimited categories and sub-categories. Database Structure: catid, parentid, .... **There are two things to do: ** 1) Improve the code of viewing the categories in rows (stop recursive querying) > "Check this link [login to view URL] 'Nested Set' is a good method, since you would not have to ever do recursive mysql querying (you will have to make a function to parse the data into a hierarchical structure) > 2) When editing: all categories are viewed on a drop down menu. It needs to have the parent row pre-selected. > Example: > Title 1 > Sub-Title a > Sub-Title b > Sub-Sub-Title a > Title 2 > Title 3 > Sub-Title a > > If editing 'Sub-Sub-Title a' then preselect 'Sub-Title b'. > If editing 'Sub-Title b' then preselect 'Title 1'. > It editing 'Title 1' then preselect top row in drop down menu saying 'Top Level'. > > *Look at example code attached.* > > **TO DO SUMMARY: ** 1) Stop the recursive querying. 2) Make parent category selected in drop down menu. THE REST OF THE CODE AND DESIGN HAS BEEN DONE. **I'm looking to spend around $5 - $10.**
