Target's global navigation features wide, multi-column drop-down menus that stretch to the full width of the page layout. The columns in the drop down show hierarchical lists of product/section contents using font weight and indentation, and additionally allow the company to promote special events.

1. Drop down for the "Women" section shows a multi-column hierarchical list of all product sub-categories.
2. The "See All" menu item allows the site to show other product categories that aren't being featured.
