selectable setting

This setting is a boolean setting. It specifies whether you can select the class that is used for a plug-in parameter. If true, the plug-in parameter appears in the formula parameter list as a class name and a Browse button that lets you select a descendant class as well. If false, the plug-in parameter does not appear at all, and its sub-parameters are listed as normal formula parameters. In this case, it looks like the plug-in parameter is replaced by its sub-parameters.

The selectable setting defaults to true, so you only need to specify it when you want the plug-in parameter to be non-selectable. It can only occur inside a parameter block for a plug-in parameter.

Example:

default:
  MyClass param MyClassParam
    selectable = false
