function doOnLoad(){
   // initialise layout
   myLayout = new dhtmlXLayoutObject(document.body, "2U");
   myLayout.cells("a").setWidth(250);
   myLayout.cells("a").setText("Folders");
   myLayout.cells("b").hideHeader();
   myAccordian = myLayout.cells("b").attachAccordian("accord");
}

When I try to attach an accordian to the cell I get an error message telling me that attachAccordian is undefined.

The correct method name is attachAccordion This method does’t get any parameter.

myAccordion = myLayout.cells(“b”).attachAccordion();
