Item subtypes use the view mapping resources defined for their parent item types automatically. If your subtype is appended to an out-of-the-box item type, its new properties will display by default on the first tab that you see when an item of that type is selected. If the item doesn’t use tabs, the properties will appear alongside the other properties in the Details pane.
For subtypes of custom item types, examine the parent types’ item mappings and item view mappings:
Locate the item mappings named for the item type. If you can’t find them, the item uses the default item mapping for all item types, and all the subtypes’ properties automatically display in the Details pane.
If you find item mappings, check the
attributesproperty for restrictions on the properties that can display. For information on displaying properties, see Specifying Properties to Display.Also, check the
viewMappingsproperty of the item mapping to see if it has any item view mappings. If it does, the item’s properties are split across tabs defined by the listed item view mappings. Review theattributeValuesproperty of each item view mapping to see if your new properties are added automatically. If not, add them manually. See the Specifying Properties to Display section.
For instructions on making other changes, see Custom Item Types and View Mappings.
