When we expand all nodes of a dhtmlxtree and then collapse just few of child nodes and then main the parent node.Tree drops from its original location .I tried replicating it in the dhtmlx.com site itself and I was successful.
dhtmlx.com/docs/products/dhtmlxT … close.html
Please check the screenshot attached.(Not able to attach images .)
Works fine for Chrome and Mozilla.
Looking Forward for help.
