Only one node within a parent can be expanded at the same ti

Hello,

It is possible that Only one node within a parent can be expanded at the same time



Thank you

Can be achieved through onOpenStart event
In case of dhtmlxtree it will look as

tree.attachEvent(“onOpenStart”,function(id,state){
if (state==-1) //opening
tree.closeAllItems(0); //close all other branches
return true;
})
