Using User-Defined UI Properties
After you give a name to a user-defined UI property, you can use the property by using the appropriate JavaScript syntax.
For example:
The UI property name is ExcludeAtt.
You can use the UI property name with the following JavaScript syntax:
attPropSet.GetProperty(".ExcludeAtt")
Note: You must include a period (.) before the name.
For an example of how user-defined UI properties can be used, see the use of the UI variable in the topic Creating a New Base Theme Template.
