HI: we're can I set that a particular item is leading, primary or secondary in a category ?

TIA

The leading number of items can be set as well as primary
The items are selected in the "order" they are retrieved
so if you set leading to 2 and order to Oldest First,
the leading items will be the first 2 that were created and still published
the primary number will pick up from there

Thanks William. Now I understand it.
