J-BusinessDirectory - Need help with views for Categories and SubCategories

Need help with views for Categories and SubCategories.

1. When viewing a category, I want to show subcategories - hoping to add list of 'Subcategory/Subcategories' names and links to show when clicking More.
   
   
2. Also when viewing a subcategory, how do we show the parent - hoping to add back arrow with 'Parent' name and link above image and description.
   
   
3. Need to fix when viewing a category the left sidebar ('Categories' ... 'Types' etc.) is empty when viewing a subcategory that has no listings under it.
   
   
4. I want to add simple next / previous arrows when on categories and subcategories - hoping to allow visitors to easily scroll through all categories and subcategories
   
   

Hi,

The category/subcategories should be shown in the search results filter and also on the search results breadcrumbs.

George, in reply, please confirm or describe what we should be seeing, as when in a category and subcategory: (a) Search results filter shows 'Categories' - id does not specify 'Subcategories' and (b) I now see 'search results breadcrumbs' and that is good for 'Parent' (item 2 solved)

I still need help with items (1) (3) and (4), even now with companies imported and we now have subcategories with companies under them. Please, what file(s) / template file(s) will I need to edit to add these features myself? Any hints that will help me accomplish these will be much appreciated.

UPDATED, please help with:

(1) When viewing a category, I want to show subcategories - hoping to add list of 'Subcategory/Subcategories' names and links to show when clicking More

(2) SOLVED - no need for back arrow to 'Parent' as breadcrumbs work well for this

(3) Need to fix when viewing a category the left sidebar ('Categories' ... 'Types' etc.) is empty when viewing a subcategory that has no listings under it

(4) I want to add simple next / previous arrows when on categories and subcategories - hoping to allow visitors to easily scroll through all categories and subcategories
