Inserting a page into a block.

Hi,
Maybe I didn’t understand your request correctly, but you cannot insert an image gallery directly inside a block. Instead, you can create a section with an image gallery, which means adding a row that will contain the gallery.
To do this, edit the page using tagDiv Composer. From the left sidebar, select Cloud, then search for Gallery. After that, import the gallery layout you want. It will be added at the bottom of your page, and you can simply drag and place it wherever you want on the page.
Alternatively, you can use a dedicated gallery plugin that provides shortcodes. In that case, create the gallery using the plugin, copy the shortcode, and then add it to your page using the Shortcode element in tagDiv Composer where you want the gallery to appear.
Thank you!
