I am using magento 1.8 and I want to customize sidebar items in first-level categories. for example, I don't want the filters in first-level category page, But it should be in the lower level categories. Is there anyway to implement this?
Its pretty simple to manage from Admin section of Magento. In
Catalog >> Manage Categories >> Select Category >> Display Settings you will see one section named
Is Anchor is set to No, the navigation filter will not be displayed. If
Is Anchor is set to Yes, navigation filter will be displayed.
In your case, I think what you will be trying to achieve is when clicked on first level category the subcategories will be displayed with no filters.
To remove filter from top level category, you have to simply make the
Is Anchor to No for that category.
For rest of the child categories make it
Hope it helps!!
