Create a class with article code name. New tabs and fields will appear on the form after saving the class.
The code name of each data element (class, attribute, view, and others) is the app identifier and must be unique in its context. For example, an attribute name is unique within a class.
The name can only consist of characters a-z, A-Z, 0-9 and hyphen. Use a single style of writing code names (recommended is lowerСamelСase, when all words are spelled together with a capital letter except the first).
Select a Attributes tab. A panel with available commands will appear when you hover over attribute table.
