Design Appearance of Module

New to HikaShop, and somewhat to Joomla for that matter. On my development site at silverconnection.cloudaccess.net I would like to replace the default catalog layout that came on the site template with HikaShop. In the left column, there are two modules. The module named Jewellery Categories is the default that came with the template using the DJ-Catalog2 extension. Underneath that is the HikaShop module that I want to replace the default module with. I'm wondering how I can change the design/appearance of the HikaShop module to look like the default module?

Thanks for the reply. I did create the module by following your tutorial of Categories Within a Module. It functions fine and each category within the module goes where it should. To be more specific, I'm wondering about the CSS aspect of the module. I have the css for the default template module contents, but from there I can't figure out where to put this code in the hikashop css file at System > Configuration > Display > CSS > Front-end CSS File. So I am trying to make the cosmetics of the new hikashop module exactly like the default module above it. Once I have that then I can unpublish the default module.

By the way, interestingly enough, the module title inherited the default css but the category links within the module doesn't.

Ahh, you made my day. I put _menu there with no luck but (space)menu worked perfectly. Can't thank you enough.
