I discovered this shortcode used over a year ago: [wpdm_frontend flaturl=0 logo="logo-url" hide="settings,images,tags"]
This is now active on this page: https://hddsite3.com/upload-page-old-shortcode/
Is this still valid code? If yes, we can password-protect this page and anyone with the password should be able to upload a file and assign the correct category, so it will show up in the correct place in the site, based on the shortcode containing the category ID.
For instance, this page has category ID “agenda”, which brings all uploads in that category into this page: https://hddsite3.com/meeting-minutes/ (password is Quaker)
Is this the intended use for this shortcode? If yes, this solves my problem. With this shortcode [wpdm_dropzone] the person uploading documents is not able to assign a category, which is a problem.
