13.1.4 Editing Page Items
Edit item attributes to control how an item displays on a page.
For example, the Type attribute determines if the item displays as text field, text area, checkbox, date picker, switch, hidden item and so on. Depending upon the item Type, item attributes can determine where a label displays, how large an item is, and if the item displays next to or below the previous item. Item attributes also control item behavior such as the item’s default value, whether the item displays conditionally, or if the item is read-only.

13.1.4.5 Changing an Existing Item to Use Quick Picks
Quick picks enable users to select predefined values with just one click, rather than typing in text or selecting from a list of available options. If the item type supports quick pick selection, use the Quick Picks attributes to define up to ten selections that display under a give item. Clicking on a quick pick sets the value of item. The following example shows quick picks for 5%, 10%, 15%, and 20%.

13.1.4.9 Configuring Item Attributes to Warn Users of Unsaved Changes
Developers can use the Warn on Unsaved Changes item attribute to specify if the page item should be included in the unsaved changes check. This check warns the user when they try to navigate away from a page and when the page contains unsaved changes. Items not based on a database column (for example, a search item) may not need to be checked. For those items, set Warn on Unsaved Changes to Do Not Check.
To configure the Warn on Unsaved Changes attribute:
Tip:
The Warn on Unsaved Changes attribute is implemented using theapex.page.warnOnUnsavedChanges
API.
