For Stephen P, I have a 2 column radio button, have a play with this, I am looking at replacing the current version with just 1 version but accepts multi columns based on the number of lists provided. Easy to add a "Other".
For Bsmiths I was wondering if it was easier to not have a dynamic block but rather a block for each type a bit more old school. You can use a tool palette or like me the older menu images.
