Enable and Disable input/output subsystem's ports in Simulink

Hello,

I created a subsystem with a mask with multiple "checkbox". The mask is used to interact with the subsystem (e.g. set constants) and choose parameters with checkbox.

I want to obtain the following behaviour:

• According to the value of checkbox1 (choosen by hands by the user when he set the parameters of the subsystem), an additional output port appears or desapears in my subsystem.
• According to the value of checkbox2 (choosen by hands by the user when he set the parameters of the subsystem), an additional input port appears or desapears in my subsystem.

How to to that?

Thanks

Variant Subsystem now supports various number of Inports and Outports of its variants. You can do it using the Variant Subsystem block without mask.
