Shortcode

Dynamic Galleries extends WordPress’ native [gallery] shortcode, by providing support for additional shortcode attributes, allowing dynamic galleries to be built.

There are two ways to insert Dynamic Galleries into your content:

  • Using the Insert Dynamic Gallery button
  • Manually adding attributes to your existing [gallery]

When editing a Page, Post or Custom Post Type using the TinyMCE Classic Editor, you’ll see a button to the right of the Add Media button above the Visual Editor:
Media Library Organiser: Dynamic Galleries: Insert Dynamic Gallery Button

Click this button, and a modal dialog window will be displayed, where you can specify several attributes for your Gallery:
