Help me Please with multi Checkboxes.

I know that you can set labels and values on radio buttons, I want to do the same for multi-checkboxes as I want different checkboxes depending on previously selected options. Is this possible or do I just have to layer hidden checkboxes on top of each other and only show one.

It is possible. See:

Please make sure to follow these guidelines . - do not post the same question multiple times.
