When I put three multi checkboxes on my site, clicking anything in the second or third multi checkbox unchecks everything in the first one. I want customers to be able to check whichever items they want. Is there a better way to do this than creating a bunch of individual checkboxes?
In this screenshot, the first column (Multi Checkbox 1) has checked items, but checking anything in the second column will uncheck all items in the first column. This makes it impossible for a customer to check everything they want, unless I do individual checkboxes, which are a chore to place and line up one at at a time.
