Delete (Action Choice)
Reference
Description
The Delete choice includes the following:
- Delete
- An action choice that removes selected elements. The space they occupied
is usually filled by the remaining elements in the scope of selection.
- Delete to Trash
- An action choice that removes selected elements (generally objects) and
puts them into the trash. The space they occupied is usually filled by the
remaining elements in the scope of selection.
When to Use
- Recommended
- Provide a Delete choice if elements can be removed. Depending on the type
of data and view presentation, either compress or do not affect the window
previously occupied by the deleted element or group of elements.
Guidelines

- If only objects are selected, the Delete choice should not be available in
the Edit menu. Provide Delete to Trash in the Selected menu instead. If the
selection scope includes only objects, then do not provide Delete in the Edit
menu.
- Recommended
- If the elements selected represent links or references to objects and you
want the user to be able to destroy the underlying object, do one of the
following:
- Provide separate choices (for example, Delete or Delete to Trash).
- Make Delete to Trash a cascaded entry through which the user can
specify whether to delete the links or references or the underlying
objects.
