I have been trying to tweak the training catalogue page that suffices the following requirement; however, didn't get a proper lead as such: I want the course categories filter to first filter based on the primary category, and then further refine the filter based on the subcategory, and so on. Example terms in course category vocabulary: Fruits Apple Orange Mango Vegetables Potato Tomato If I select Fruits in the first filter, I should display all the courses that are associated Fruits vocabulary term (including content associated to Apple, Orange, and Mango). Unfortunately, the Simple Hierarchical Select module displays no result in such scenarios. Additional modules and profile used: Opigno LMS profile version 1.19 Views Dependent Filters module Simple Hierarchical Select module It would be appreciated if any one from the forum could help me on this. In case you need further details in order to suggest me a solution, please don't hesitate to ask for it.
