Categoritzing Simscape parameters in the block parameters

Hello,

I'm currently working on custom simscape components.

Looking at the block parameters of closed source components from Mathworks like the DC-Motor (Simscape/Electronics/Actuators & Drivers/Rotational Actuators) I see that parameters can be organized in tabs:

However I haven't found any reference of the parameter syntax for the ssc source files enabling me to categorize the parameters that manner.

Thank you very much for your answer.
