All the default functionality is active and untouched for our Zen Cart themes.
Only one setting parameter is disabled for our Zen Cart responsive themes in the admin area (column width) due to the fact the responsive feature requires a special layout, so we created a new layout that is based on "div" HTML tag, not the "table". Columns width is defined automatically when you change 3 or 2 column layout in the admin area.
The feature allows you to enable the category menu at the top. The categories appear automatically when you create them in the admin area. The menu appears instead of the "Home, New Products, Specials, etc." links at the top navigation. You can turn it on/off via admin area.
You can easily set 3 or 2 column layout via Zen Cart admin area and product columns will stretch automatically. Set the number of the product columns in Zen Cart admin area according to your needs. Categories Dropdown menu feature allows to get the second level subcategory items directly. Shopping cart dropdown menu makes easier and faster access to the purchases you made. A stylish design of category page gives your online store professional appearance. Multilanguage is supported. You can easily change the language or currency via dropdown menu.
