Due to various differences in the implementation of such styling, we have opted for not styling the checkboxes in ListBox and combobox.
However, that [integration between form decorator / listbox] is something requested every now and then, so we have created a public item for customers to vote on:
When the item receives enough attention, or when it's time is due, we'll implement the integration.
Note that the Ideas and Feedback portal is the successor of PITS. Any and all feedback, be it on this item, other items or new items is highly appreciated.
