Insert a gallery of documents in a post or page from a folder in your media library created with <a href="https://devowl.io/wordpress-real-media-library/" rel="nofollow ugc">WordPress Real Media Library</a>.
<h3>Requirements</h3>
This plugin is an add-on that allows you to use the following plugins together, which must be installed:
<ul>
<li><a href="https://wordpress.org/plugins/document-gallery/" rel="ugc">Document Gallery</a></li>
<li><a href="https://devowl.io/go/codecanyon/real-media-library?source=document-gallery-for-real-media-library-wordpress-org" rel="nofollow ugc">Real Media Library</a></li>
</ul>
<h3>How to use it</h3>
Watch the following video for a brief general introduction to <a href="https://wordpress.org/plugins/document-gallery/" rel="ugc">Document Gallery</a>:
<iframe loading="lazy" class="youtube-player" width="750" height="422" src="https://www.youtube.com/embed/Xb7RVzfeUUg?version=3&rel=1&showsearch=0&showinfo=1&iv_load_policy=1&fs=1&hl=en-US&autohide=2&wmode=transparent" allowfullscreen="true" style="border:0;" sandbox="allow-scripts allow-same-origin allow-popups allow-presentation allow-popups-to-escape-sandbox"></iframe>
Just install this plugin and you can use the following short code. The <code>rml_folder</code> attribute is the ID of the folder created with Real Media Library.
<pre><code>[dg id=-1 rml_folder=28]
</code></pre>
How do you get the folder ID? Go to “Media” in your WordPress backend and select the folder you want to know the ID of. The URL in the address bar of your browser ends with “/wp-admin/upload.php?rml_folder=4”. In this example the folder ID is 4.
This plugin is a free micro add-on for Real Media Library with limited support.
