Gallery of galleries

If you want to create a gallery that has its own set of images for each gallery, this feature is not directly available in the plugin but you could still achieve it manually.

1. Create individual pages for each galleries and put your images on the page. For example a page named Wedding, Wildlife etc with their respective masonry gallery. You could use any of the two available modules on these pages.
2. Create a main page where you put your featured images and link the images to respective URL. This is how you can do that.

In this scenario, when you display the images of main gallery (from step 2), users will be taken to the wedding or wildlife page that will have their own set of masonry galleries.
