Ontab items for Multiple Choice Enumeration Type: how to create

[Sam Karli]

I'm in an UI-heavy project (effectively recreate "ID and Properties" panel on the Infobox as a modeless panel can be shown always), and on the List Box some controls are quite complicated to be recreated. Most complicated is this List with the multiple checkboxes:

Among Example projects there are similar stuff (DG Test/AttributeList Control/Text Selection Item is kind of similar, rather to the Single selection stuff), but the class behind it is attribute-related I think.

Is it possible to recreate it for properties, and if there is, how?

Thanks in advance
