.. _editing-items: Editing Items ------------- GUI Form ......... Where user and model permissions allow it, an item can be edited and saved from a GUI form: * Displayed field names are customizable and provide tooltips according to a Field Display Policy for the model. * Form GUI Rules control the default field availability and pre-populated values. * When a form is opened, form details are initially rendered using cached data. While loading the non-cached data, the **Save** button on the button bar is unavailable, and replaced by a 'spinning wheel'. Once the non-cached data has been loaded, the 'spinning wheel disappears and is replaced by the **Save** button. * A form may also provide an on-line help icon to guide a user in editing it.
