Portlets
Portlets are dynamically generated (or static) content views that can be displayed in special areas of the site layout. There are two basic kinds: fixed-column portlets and content well portlets.
Fixed Column Portlets
These portlets are the kind you see most often—appearing vertically in the far left and right-hand columns of the layout.
Content Well Portlets
These can be positioned horizontally, above or below the normal content.
