Ok, So i think we have a little misunderstanding. Your plugin does a few things,
1. Displays a list of “packages” to a page using “link-templates”. Correct?
2. When you click on one of those packages listed in the “link-template” explained on the line above, you THEN are brought to a detail page that shows all the details of the package and also allows you to download the file.
Now, that we both understand that, your not answering my question. I asked how do i display the “page-template” for that package and your telling me how to show a template for a specific package which is not what i asked. If i click on the package and then get taken to a detail page for that package, how would i add a shortcode for that package when that page is dynamic to whatever package is clicked.
After hours of looking and trial and error i think i had to finally find my answer by editing the file and changing the settings on how i want it to look.
While im at it, you and your docs keep pointing us to this page: https://demo.wpdownloadmanager.com/wpdmpro/ready-to-use-templates/, which is a waste of my time since I already looked at that page and i already chose what one i want my detail page to look like but NO WHERE on that page does it tell me how to achieve that look and feel. All it does is show me what your software can do as to try to make a sale but i already purchased your plugin.
Your features of the plugin and nice ways on how to make it look is what made me purchase, but its not very easy to find how to use it other than the install and then gotta kinda dig through lots of stuff to still not find the direct answer.
