Workaround
commented out in the attached example:
zk.afterLoad('zul.menu', function() { var xMenupopup = {}; zk.override(zul.menu.Menupopup.prototype, xMenupopup, { open : function (ref, offset, position, opts) { if(!offset && !position) { this._reverseDir = this._parentPopup()._reverseDir || false; if(this._reverseDir) position = 'start_before'; } xMenupopup.open.call(this, ref, offset, position, opts); }, _syncPos : function () { var parentPopup = this._parentPopup(); if(parentPopup && zk(this).isOverlapped(parentPopup.$n(), 5)) { this._reverseDir = !this._reverseDir; var position = this._reverseDir ? 'start_before' : 'end_before'; zk(this).position(this.parent.$n().getBoundingClientRect(), position, {}) } }, _parentPopup : function () { return jq(this.parent).closest('@menupopup').zk.$(); } });//zk.override });//zk.afterLoad
