Extend an existing typelist definition

Before you begin

If you need to use a file name suffix for your typelist, see Add a file name suffix to data model extensions.

You can extend non-internal typelists that are in the following Guidewire Studio location: configuration > config > Metadata > Typelist.

In Guidewire Studio, in the Project tool window, navigate to configuration > config > Metadata, and then expand Typelist.
Right-click the non-internal typelist that you want to extend, and then click New > Typelist Extension.

The file that you want to extend must be non-internal and have either a .tti or .tix file extension.
In the Typelist Extension dialog, Studio displays the name and location of the extension file it will create. Click OK.

Studio displays the name of your new file in the Extensions > Typelist folder and stores the new file at the following location:

configuration/config/extensions/typelist

Studio then opens your new file in the appropriate editor.
