i have tried extjs tree-panel below getting table-1 column1 parent node not getting column2 child nodes ?

ext .onready(function() {     var tree = new ext.tree.treepanel(             {id : 'treepanel',                 el : 'tree-div',                 usearrows : true,                 title : 'export',                 autoscroll : true,                 width : 250,                 region : 'west',                 animate : true,                 enabledd : true,                 containerscroll : true,                 enablekeyevents : true,                 collapsible : true,                 split : true,                 rootvisible : false,                 border : false,                 // auto create treeloader                 dataurl :'<c:url value="/customize/exportreport.do?method=getexport"/>',                 root : {                     nodetype : 'async',                     text : 'root',                     draggable : false,                     id : '-1',                     expanded:true,                  //here children node cannot able rendered have made mistake ?                     children:[{             text: reportt‌​ype, //treenode java class variable              leaf: true }]         }                 } }); });

if understand well, hardware child of root , hardreport child of hardware.

i think there no direct solution in extjs.

  • you change backend send correct data
  • you have manually parse json
  • you load data in first tree store, , build second tree store looping through first.
