I have a series of categories, for example:
2010 Presentations etc
Beneath each category are a series of downloads...PDFs etc.
When the user clicks my "Downloads" pages (which currently contains wpdm_tree shortcode) I'd like them only to see the top level categories, which they then need to click to see the child objects of that category.
I cannot work out how to do that, though? I have tried ticking the appropriate categories of each downloads but the tree view seems to show literally everything?
