2. In that section configure a button to right side and on click of this button a modal dialog should open.
3. In the modal dialog create a button with onclick open Menu Item action.
4. While the menu items are displaying scroll the horizontal scrollbar present at parent body.
5. Observe that menuitem list panel is moving.

Root Cause

A defect in Pegasystems’ code or rules.

The new CSS based modal has position fixed but the templatized menu is absolute hence the menu scrolls along with the document.
Also user has not upgraded to new menu controls and included older version of jquery in treenavigation harness.


​Perform the following local-change steps:
  1. Upgrade old menu to new menu rule and remove the older version of jquer.
  2. Then install Hfix-25760 to resolve the issue.
