The Masonry layout
The Masonry layout is available in Spotlight PRO only.
It provides a more creative way to display your Instagram feed by having all posts displayed in their original aspect ratio (full size, not cropped to squares).
By default, the layout is displayed in 3 columns, but this can be changed at any time from the Feed design options. Set the number of posts to show and the number of columns to create a masonry design that works for you.
