I also find documentation a bit unclear. For example to init a widget is enough to write
dummy = $(
but if you want to use API you must explicitly call data("kendoPanelBar");
panelBar = $(
otherwise you get error message when you call expand/collapse or some other functions. This sort of things are not pointed out in documentation.
in the configuration section of PanelBar widget is for example explained expandMode
expandMode: String(default: multiple)
but what are the other options. It is somehow logical that it would be single but it's not specified in configuration section.
