I have a list of options (yes/no) I will like to be able to drill down into on the data explorer.
So for example:-
Cat one Type Van Car
Type two Transit (type of van) ford (type of car)
Type three
Escort (Type of Ford, Type of Cat)
I would like when I first open dataexplorer for only Cat one options to be avaliable, Then when I click on an option, only the relivant options from cat 2 to show. And then the same into level 3.
Not presently. You can achieve a 2-tier drill-down using filters for the type one, selection in a view for type two, and displaying the resulting data using a view with Data Subset set to "Selected data".
I have reclassified this as an idea - please vote. In short:
Hierarchical multi-field category filter, as a tree of checkboxes; or, contextual filters, which show/hide options according to their availability given other active filters.
