Problems with dhtmlxMenubar

I’m use the context menu( dhtmlxMenubar1.3) with a tree in large page(scrolling )

When I right-click on the tree node.the contextmenu can’t correct display ( menu position is incorrect)

How should solve?

P S:sorry my english is very poor :frowning:

If context menu position shifted to some constant value, you can add correction as


where x_cor and y_cor correction for x and y axis
