Create a new tag
Create form
On this form, the only necessary information are name (the actual display name of the tag), slug (a unique value that represents the new tag), table name (the table this tag belongs to (products,orders...)) and type (group of tags, like default, other...).
When a new category for tags is required, a new tag with that category can be crated with the "create" form.
Tag editor
In the tag editor, all tags are grouped into categories. To add a new tag into a category, open the category section and press the "Add tag" button at the bottom of the list.
