Because of the infrequency of use, save valuable screen space by only showing the full list of items on demand. Solution [image of Item list] A list of items from which a picker dialog is launched. The target list is not directly editable. Provide an "edit" or "add" button at the bottom left of the list. If the order of available items can be changed, provide up/down buttons to the bottom right of the list. Drag and drop may also be used in addition. [image of Picker dialog] The Picker Dialog displayed. On clicking the "edit" or "add" button the Picker Dialog is displayed above the target list while ensuring that the target list can still be viewed. The Picker Dialog includes: the complete list of available items a title of the available items located at the top of the list a checkbox for each item to the left of the item name (see Rich Lists if more information must be displayed) a close button to the bottom right of the dialog Upon selecting a checkbox the item is immediately displayed in the target list.
