Use a "Load More" button

See the Load More Button Pagination in action

With a "Load More" button your visitors can decide if they want to see more items of the grid. You pick the number of items shown on initial load and how many items get loaded on each click.

Optionally enable  Load Posts on Filter to immediately load all items that match any filter selection your visitors make.

Use the Button Styling tab to change the look & feel of the button itself.
