Advanced smart layout abilities ensure that the Ribbon Bar makes the most efficient use of the available space. Smart layout allows each item to have multiple image sizes. The smart layout will display the largest images when enough room is available and automatically display the smaller icons when space is tight. When space is abundant, large images with item captions are displayed, if space is limited, then only small icons with no captions are displayed. Items are always only a few clicks away, groups with insufficient space are displayed as a popup button which displays the entire group as a popup. Ribbon Bar is always adapting to its environment to provide a perfect fit.
