You can create additional tabs in a property sheet when you want to improve extended attributes presentation. By default, extended attributes are listed in the Extended Attributes tab of an object's property sheet. This list gathers heterogeneous attributes in alphabetical order. You can create additional tabs to better present extended attributes and make it easier to enter their values.
Additional tabs allow you to address the following problems:
You have a very large list of extended attributes; you can display them in different property tabs with a meaningful title in order to retrieve them easily.
Extended attributes are of very heterogeneous types and need to be organized logically instead of alphabetically.
Extended attributes are related and need to be grouped together in order to clearly indicate their dependency link.
You need to define the extended attribute value using the appropriate editor.
To create an additional property tab you use the form extended feature available from the Resource Editor. You can create a "Property tab" form for a selected metaclass, stereotype or criterion and select the extended attributes to display in this tab.
