hello
Drag and drop is coming this error but sometimes it works

$('#CompanyList').jqxListBox({
source: companies,
displayMember: "CompanyName",
valueMember: "CompanyID",
height: "350px",
width: "300px",
allowDrag: true,
allowDrop: true,
theme: 'summer',
selectedIndex:0,
theme: 'arctic',
});
I thought it might be a mistake I after use the demo
var source = [
"Instant coffee",
"Irish coffee",
"Liqueur coffee"
];
// Create a jqxListBox
$("#ModulList").jqxListBox({ selectedIndex: 3, source: source, width: '200px', allowDrag: true, height: '250px', });
I still see the same error I have a bug problem?
thank you
