I tried to used the example code shown in the above link:

PreviewWidget expandable("exp", "expandable");
expandable.add_attribute_value("title", Variant("This is an expandable widget"));
expandable.add_attribute_value("collapsed-widgets", Variant(0));
PreviewWidget w1("w1", "text");
w1.add_attribute_value("title", Variant("Subwidget 1"));
w1.add_attribute_value("text", Variant("A text"));
PreviewWidget w2("w2", "text");
w2.add_attribute_value("title", Variant("Subwidget 2"));
w2.add_attribute_value("text", Variant("A text"));
expandable.add_widget(w1);
expandable.add_widget(w2);

regardless of what number is defined in "collapsed-widgets", it always shows all of the widgets there.

Thanks & best regards,
