GWcode Categories has been updated to v1.6.1 today and I’ve also converted the plugin for EE1.
New in this version is the ability to provide multiple entry id’s in the entry_id parameter. This allows you to create a list of categories the provided entries have been added to. The categories in the list will be unique, so if entry 1 has been added to category A & B and entry 2 has been added to category B & C, the result will be A, B & C instead of A, B, B & C.
General information:
This MSM compatible plugin for ExpressionEngine 1 & 2 allows you to list your categories (nested or linear) based on certain conditionals, such as a minimum depth, maximum depth or fixed depth. It can be used to easily display a category based dynamic breadcrumbs trail for example, or a category’s child categories.
