To create a folder in a list with hierarchy of folders and items, in the list form, on the All actions menu, click Create group.
If you select a folder before creating a new one, the selected folder becomes its parent (in Hierarchical list or Tree view mode).
In some applications you have the option to specify a parent in the item creation form, irrespective of the mode and current folder.
Similarly to creating a list item, when you create a folder, you can edit its properties in the folder creation form.
1C:Enterprise does not differentiate between the codes of list items and folders, that is why folder codes and item codes cannot be identical.
Other operations related to creating and editing folders are identical to item creation and editing.
