Hi, Here''s a situation: A product belongs to multiple categories and the categories are top menus of a site. I want to highlight the category of a product when the product detail page is loaded. If there''s some context, I can determine which category should be highlighted. (For example, I can track the categories that a user selected). But sometimes there''s no context (for example, the user visits the page directly without getting through categories). How can you solve this problem? Thanks.

I was not clear about this. Product and Category are m:n relationship.

I think you are saying category has_many products through categoryship and product has_many categories through categoryship also. In that case if you have a product then the categories are available as @product.categories. I am not sure what your question is.

The problem is that @product.categories is multiple. I need to highlight only 1 category for the product and show only 1 breadcrumb. If there''s some path that the user took, I can select the category but if there''s no such context, I don''t know what to do. I can make my own policy but I want to know how other developers are doing. Thanks.

Our top menus are categories. I need to highlight the category. Do you have any good idea for that? Thanks.
