Assign Attributes Types to Categories
When an Attribute Type is assigned to a Category, the Attribute will appear in the Attributes Panel. The Attributes Panel is part of the Item Entry screen, and appears after a Category is selected.
Attributes may be assigned at any Category Level - 1, 2, or 3. When an Attribute is assigned to a Level 1 Category, the Attribute Cascades to that Level 1 Categories’ Level 2 and Level 3 Categories. This means the Level 2 and 3 Categories Inherit Attributes from the Level 1 Category of which they are a sub-category.
When an Attribute is assigned to a Level 2 Category, that Attribute Cascades to its Level 3 (sub)Categories.
Note: It is only necessary to assign an Attribute Type to one Level in a particular Category. Do not assign an Attribute to more than one Category Level for a particular Category.
Example: Women's Apparel Sizes provides a good example of why one would choose to assign Attributes at a level other than Category Level 1. Dresses, Pants, and Tops may all use pretty much the same set of sizes, but shoe sizes are a different matter. Assigning the Attribute Women's Size to Dress, Pants and Tops at Level 2, and Women’s Shoe Size to Shoes at Level 2 lets you limit the number of Sizes appearing in each Size list when entering items.
In other words, when entering Dresses, which have sizes like 2, 4, 6, 8, 10, 12, 14, 16, 18, 20 etc. you’re not also looking at shoe sizes such as 4.5, 5, 5.5, 6, 6.5, 7, 7.5, etc.
