We have recently added a new option to the reCommerce2.0 admin area that will allow you to customize the Brands menu.

1. From the admin area, click on Settings > General Settings

2. Click on the Resaleworld Options link on the right side of the next page

3. Search for the brands drop down option in the Product Options section

That will allow the brands menu to appear as a drop down.

With the drop down option disabled, you will see a brands list.

Hope this helps!
