if you know joomla , you will know it's only support this structure
SECTION >> CATEGORY >> ARTICLE
and you can't add any more sub-level categories
what i want is the ability to add subcategory where the subcategory will appear under the parent category in the front end
i also want to be able to add articles to multiple categories from the back end "not very important"
the most important thing is ability to add unlimited subcategories as needed
