How to show categories of the same level?

General General Questions
1

I need to show a list of categories at the same level as the current selected category on the sidebar.



For example: If I am at [url=“Instant Demo - CS-Cart Multi-Vendor Demo Try Free for 15 days”]Instant Demo - CS-Cart Multi-Vendor Demo Try Free for 15 days

I want to see Womens, Shoes, Watches & Jewelry.



Bonus: I would also like to show these categories only if the current category does not have any

children categories.



Anyone have any idea how I could accomplish this?
