The only way I have found to make a bundle item required with no options in a bundle part is to make a separate 'option' for each part, select the radio button type, enter the quantity and disable user quantity, and select the default button.
This creates a messy user experience with extra lines and option titles, when there really should be a way to put all parts under a single 'option' list. So basically an input type of 'none' instead of a checkbox etc.
I don't want people to be able to de-select any item, but having each item under a different 'option' looks really messy compared to having all the parts in a checkbox type list under one option.
Anyone found a workaround for this?
Thanks,
