Im trying to open a combo box on the same position of the button:
So I overwrite the function of contextMenuTool, to set the position of object:
"toolManager.contextMenuTool": (contextmenu, obj) => {
contextmenu.position = new go.Point(obj.position.x + 20.0, obj.position.y + 20.0);
}
Without Webix Library works, but when I activate Webix, than I receive following exceptions:
go.js:314 Uncaught TypeError: d.canStart is not a function
at La.doMouseUp (go.js:314:199)
at Q.doMouseUp (go.js:605:279)
at a.Zj (go.js:822:147)
Do you know how I can fix it and why is this happen?
