Nested categories/sub categories in KM portal

[Barry_W]

Does anyone have any information on when knowledge category/sub-category nesting will be available OOB on the CSM portal view?

Specifically, i refer to the functionality to select a top level category and view all articles in each of the sub categories.

The kb_categories are created in a nested format, so i cant understand why navigating, and searching, using a nested format is not available on the when accessing via the CSM portal.

Thanks for this information Sarup. I've enabled in my dev instance and am now testing, in Orlando. First thing i have noticed is the category list is displaying categories where there are no articles assigned, essentially empty categories. This isn't the case if you change the widget options to display categories as a flat list (with the kb category hierarchy disabled). We have our knowledge properties to omit empty categories and topics on the portal.

Is there any way to display in a hierarchy, but continue to omit empty categories?
