A Post/Item used as Intro content for a Category/Chapter or other place.

A post behaves like an Intro when it uses an Item Type such as Intro Cat, Intro Tag, Intro Front, Intro Main, Intro Sub, Intro All.

Intro items are not displayed in the regular flow of items either. Instead, depending on what you are looking at (the home page, a category, a tag page...) b2evolution will automatically select one intro item and display it on top of the regular list of items. In many skins, the intro will be displayed with a slightly different style from a regular item. See Intro and Featured Items.
