The scrollbar does not display after expanding the layout



Unable to resize the screen after expanding the layout. The scrollbar does not display and as a result unable to view the content.

Error Messages

Not Applicable.

Steps to Reproduce

  1. Add a tabbed layout group in harness
  2. Add a few section rules in a tab add so that page height is equal to the screen height at runtime
  3. Add a collapsed tree grid in one of the section rules present at end of the screen
  4. Run the case and expand one of the grid rows

Root Cause

A defect in Pegasystems’ code or rules. On expanding the window, the height is not re-calculated due to which the screen is unable to adjust.


Perform the following local-change:

1. Add the below script in the section which is not auto-generated and is included in the tab:


var setTabHt = function(){
var Tempht = $(".screen-layout-region-main").height();
$(".layout-body .custom_tab2")[0].style.height= Tempht -30 +"px";
$(".layout-body .custom_tab2")[0].style.overflow= "auto";

setTimeout(setTabHt ,100);

2. Add 'custom_tab2' custom style class in the dynamic layout of included section in the tab
