I would like to create a customizable filter widget that can be used to filter a view on a page. One type of filter uses taxonomy terms. While I can easily create a list of terms, I find I cannot create a list of vocabulary NAMES to choose from for the filter.
Ultimately, I'd like to iterate through the terms of the chosen vocabulary name and display that list of terms. So, in summary, create a widget that users can choose from a list of vocabulary names. Once that is selected, display the list of terms of that vocabulary name on the page. Is this possible?
I've tried so many different ways using views, entity references, etc but cannot get a list of vocabulary names in a field.
