A snippet to create a drop-down list of categories so that publication resources can be listed in multiple categories, pulling the categories from the pagetitles of a set of otherwise blank child resources, was working okay but then broke when upgrading to 3.0.0. The way it breaks is that instead of showing the dropdown list in the relevant publication resource TV, it merely prints the code I entered in the template variable input list options field:
I see on the documentation page below it says that the drop-down menu TV input type has been deprecated. Does that mean that it is wrong to even try to do this? If so, what is the right way of enabling a client to categorise a publication resource under one or more categories?
