Picker Dialog

Summary

A group of items that might be changed on a rare occasion (such as added, removed or re-ordered) is available to the user. 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.

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.
