There are a few different ways to create a custom page in BlockCMS. One of the ways to do this is with structured data where you can make a page a list or grid like how our templated pages are structured. Another way would be to code it in HTML. But if those won't do a great third option would be to build out a free form page. To get started building a free form page first add a new page and select "Free Form"
Then you'll want to give the page a name, a path for the url and then a subtitle and description. Then you'll be able to edit the page and customize it any way you want within the text editor.
From there any changes made within the editor will show up in the body of the page.
