Create a document with the division of products into categories

In the business process interface settings, there is a checkbox that allows you to display products by category. [file]23298[/file] [file]23299[/file] [file]23300[/file] There are these checkboxes: [file]23298[/file] [file]23299[/file] [file]23300[/file] - Display separator by product category [file]23298[/file] [file]23299[/file] [file]23300[/file] - Display a separator across all levels of product categories [file]23298[/file] [file]23299[/file] [file]23300[/file] Which allows you to see products divided into categories. [file]23298[/file] [file]23299[/file] [file]23300[/file] How can you do the same in documents? [file]23298[/file] [file]23299[/file] [file]23300[/file] That is, so that we can see the distribution of products by category. [file]23298[/file] [file]23299[/file] [file]23300[/file] If there is no such function, how much would such an upgrade cost?
