Help screen column header Sticky
From Joomla! Documentation
- Sticky. Whether or not the Banner is "sticky". If one or more Banners in a Category are designated "sticky," they will take priority over Banners that are not sticky. For example, if two Banners in a Category are sticky and a third Banner is not sticky, the third Banner will not display if the Banner display module setting is "Sticky, Randomize" or "Sticky, Order." Only the two sticky Banners will display. If the sticky banners have a fixed number of impressions, once those impressions are used up, the sticky banners will no longer display, and the non-sticky banners will begin displaying automatically.
