Hello mohammad,

Please try to set pid: item.parentId instead of pid: item.parentid.
Thank you for the interest to our widget.

Hello mohammad,

Sorry for this misunderstanding.
You could try to use getItems – receive an array with all items and each has ‘parentElement’ member and another details for this.

label – gets item’s label.
value – gets the item’s value.
disabled – gets whether the item is enabled/disabled.
checked – gets whether the item is checked/unchecked.
element – gets the item’s LI tag.
parentElement – gets the item’s parent LI tag.

(if the result of ‘parentElement’ is null – this mean it is a root, otherwise it has children)

isExpanded – gets whether the item is expanded or collapsed.
selected – gets whether the item is selected or not.

Also could use ‘hasItems’ member to check is this a leaf or not.
You could find out more details in our API Documentation.
