You can display packages from a specific category.
For example, suppose you have three categories, A, B,C and you only want to display the packages from Category B.
You can use the following shortcode:
[wpdm_category id="b" operator="IN" title="Custom Title Here or 1" desc="Custom Description or 1" toolbar="1" paging="1" orderby="field name" order="asc or desc" items_per_page="10" template="Template ID" cols=4 colspad=2 colsphone=1 async=1]
This shortcode will display only the downloads/packages that belong to Category B.
