As you may have noticed the Portfolio template does not contain any pagination. The reason for this is pagination will not work well with the isotope filters and is really only useful when viewing “All” items.
Because of this I added an option that allowed a user to limit the amount of Portfolio items shown which worked well when there is only a few items, but completely useless when there are many items.
The solution is to add an infinite scroll to the portfolio page with maybe an optional “Load More” button and allow the user to select how many items to display before loading more.
With the recent 1.1 update I decided to remove the item limit option and have the portfolio load an unlimited number of items until this infinite scroll feature is added.
