Each facet has a Child Facets tab you can use to manage the facets nested in the selected facet, by creating, ordering and deleting such child facets. On the Child Facets tab, a Child Facets Table provides the following tools:
Use Add New to display empty facet properties that, once filled in, are used to define a new facet. When you click Create, the new facet displays in the Navigation hierarchy beneath the originally selected facet.
Use the numbers beside a facet to rearrange its position in the tree. To preview the new order, click Reorder.
Use Delete beside a facet to delete it.
