Enabling a Single Option Based on a Yes/No Response
In many situations, you may want to enable or disable a single option based on a user response to a yes/no question. For example, you may wish to determine whether the user wants a particular option package.
To enable a single feature based on a yes/no user response:
1. Create a configurable module.
2. Attach a child part that represents the relevant option.
3. Add a boolean input parameter to the configurable module.
4. Define an appropriate prompt value for this parameter.
5. Add this boolean parameter to the Inclusion Option of this configurable module for the child part.
The following image figure shows an example of this technique where the Emergency Stop Option is or is not included by the value of the boolean parameter askEStop.
