Can I make my Categories work like this and how?

OK I sell Jewelry I use a couple basic techniques Chain maille and beaded and make you basic types of Jewelry earrings Bracelets necklaces ect. So what I would like to be able to do is have a Chain Maille category that has Earrings Bracelets Necklaces, ect under it and when you open on of those you get just chain Maille stuff but I wouldalso like to be able to just open the Bracelet category and See both Chain Maille and Beaded bracelets. Is this possible using Zen cart? I have been searching the forums and the FAQ but haven't seen anything yet that answers this.

You can put products in multiple categories in Zencart.

Open Admin - Catalog, find the product you want, and click the 'Copy' icon on the right (white 'C' in a blue circle). You'll see your options there.

Ok Here's my site so far https://www.skybyes.com/zen_cart/index.php?main_page=index&cPath=4 I have multiple categories the ptroblem is I want Bralets and Chain Maille to be both a main category and a Subcategory will I have to duplicate each one as a sub category to make this work?
