Hi Dennis,
Unfortunately, such a feature is not supported. If you wish, you can contact sales@jqwidgets.com and request it as a custom development service.
There is also another feature that may be useful to you – mixed check mode – this way you can make only particular items in a pop-up checkable and others – not – by separating them with a separator. Here is a demo on the matter: https://www.htmlelements.com/demos/menu/mixed-check-mode/.
