Disable parent category in menu

Hi,

Would there be an easy solution to make the parent-categories in the top menu not clickable? And perhaps even disabling  the parent categories from the breadcrumb?

Sure, the main categories have the parent_id = 0. So that should only require a simple if condition. See boxes/box_site_menu.

For the breadcrumbs. Either prevent the first category in the category trail to be output. Or slice up the already built array alternatively remove the second item in the built array. See pages/category and pages/product.

var_dump(breadcrumbs::$data);
0 Site Name
1 Main Category
2 Sub Category
(3 Product)
