The page break content block inside of the print view allows the user to break off content at a certain point and then for it to continue on the next page. This is good for when the user views the PDF preview and wants a certain content to start on a new page instead of it being started on the same page as another subject.
Note: I recommend only using this tool inside of the print view, if you are to use it inside of desktop view you may get mixed up and can be a hassle when using multiple content blocks on one page along with not being able to see a live view of when you use the tool.
Starting inside the Template editor, go to print view, located at the top bar a little to the right from center, click the PDF Icon. This will then change the view to Print view, from here this is the view of how the pdf should come out. Then, from the left side of the editor, you will want to go to the Content Blocks section, where the list of content blocks are dragged in to create a publication. From the list of subsections of content blocks, you will want to click the subsection called PDF Specials. This subsection will then display a content block called PDF Page Break. Now, you will want to find an area of the publication you will want to then break off onto the next page. When placing the content block, the content after the break will be moved to a new page, which is where the rest of the content will then continue. Click and drag the content block before the section of the publication you want to then split onto the next page while dragging the content block around the publication you will see a colored line appear indicating where that page break will be placed when you release your mouse button. Once you place the content block you will notice straight away that the content after it is then moved and continued onto a new page. You can then ensure that this change has been made by clicking the orange PDF Preview button in the top right, this will then generate a PDF that then opens for the user to view.
