On your collection list, find the 'Display Limits' settings on the element settings, and select the checkbox 'Paginate Items' and define the amount of items you want to show by default. (Before the Load More button is clicked)
Apply the custom attribute to the same collection list that you activated the Paginate Items setting on.
Add the Custom Attribute to a button element that will be used as the trigger to 'Load More' items.
