A user interface display comprises a plurality of selectable icons and a control symbol in a toolbar. The control symbol can be selected by a user to display additional selectable icons within the toolbar. The additional icons can be inserted adjacent the control symbol or in another location on the toolbar. A user can associate a set of one or more selectable icons with a control symbol. The set of icons can be displayed adjacent the control symbol or at any pre-specified position on the toolbar. In one implementation, reselecting the control symbol removes the additional icons from the toolbar. In another implementation, the additional icons are removed when one of the additional icons is selected. If the icons are positioned adjacent to their corresponding control symbol, the display position of other icons on the toolbar is adjusted to allow room for the additional icons. When a set of the additional icons are removed from the display, the position of the other icons on the toolbar is re-adjusted to remove open space between icons on the toolbar. The toolbar can include more than one control symbol, and more than one set of additional icons can be displayed simultaneously. The toolbar allows the user to include or remove additional icons from the toolbar on an as-needed basis, thereby eliminating the need for additional toolbars and leaving more space available on the display for information that may be more useful.
