dhtmlxForm master-child checkboxes

I am using dhtmlxform for my web page. I would like to know if there is any master-child checkbox control available in dhtmlxform. The expected behaviour is - when master checkbox is checked all child checkboxes get selected, however when I uncheck the msater checkbox, the child checkboxes are active and user can select certain checkboxes and leave some checkboxes unselected.

Thanks

There is no native approach.
But there is enable/disable mode like in the sample (for the radio button):
dhtmlx.com/docs/products/dht … bject.html
Or you can use tree: dhtmlx.com/docs/products/dht … boxes.html (Three state checkboxes)
