Go to the ‘Content’ tab and then select ‘Pages.’ Select the ‘Page Layout’ icon on the home page (which is the icon in the bottom right corner shown below).
Select the ‘Collection Items’ icon on the slider you wish to add the film too.
Click on the ‘Add a Film’ button to add a new film to the collection.
In the ‘Select a Film’ field, start typing to find the film you want and select ‘Add’. You can change the order in which the films display by click and dragging on the poster to the desired position.
Select ‘Save’. It may take up to five minutes for the changes to show on your site and you’ll need to refresh the page to see the latest changes.
