ProductCategoryFields of type checkbox can have multiple items selected. Currently the results come back as a comma delimited string in "Value". If only one item is selected then "OptionLabel" will exist, otherwise "OptionLabel" won't exist. OptionLabel is the friendly name for the checkbox.
It would be nice to be able to use the OptionLabel when multiple items are selected. The solution is probably to have the ProductCategoryField support a loop of selected items. Then OptionLabel can be used. I assume it would be within here:
<!--@LoopStart(ProductCategories)-->
<!--@LoopStart(ProductCategoryFields)-->
I assume that fields of type checkbox should have a loop in here so that you can enumerate over them.
<!--@DwTemplateTags-->
<!--@LoopEnd(ProductCategoryFields)-->
<!--@LoopEnd(ProductCategories)-->
