How to disable some of check box options inside of Matrix

is there a way to completely hide the checkbox? It makes no sense to view an item that you can´t choose. I have included a sample image with different options. The version one (please see the image) would be my favorite. Is there a way with Custom CSS hide individual answers. I do not want to edit the source code of the form.

Yes it is possible to completely hide the checkbox. CSS code on my previous post will disable checkbox options. If you want to hide them then add this CSS code:

#input_4_1_3 {

pointer-events : none;

visibility: hidden;

}

#input_4_2_3 {

pointer-events : none;

visibility: hidden;

}
