Tree Grid not displayed correctly in Repeating tab layout



When a tree grid is included as a section in a repeating tab layout, the tree grid's rows are not aligned properly. The column that shows the tree structure has row heights taller than the other columns. Upon expanding the tree item, the tree item's child rows don't get displayed. This does not happen when a tree grid is included as a section in other layouts (e.g. dynamic layout).

Error Messages

None. Observed an undesired behavior where the tree grid rows are not properly aligned and expanding the tree does not display the tree child item rows.

Steps to Reproduce

Place a tree grid with expandable rows within a tabbed repeating layout.
The first column will be out of alignment and frozen.

Root Cause

The root cause of this problem is a defect in Pegasystems’ code/rules. The height of the row was set to 34 px.


This issue is resolved through the following local change:

Customize py-enduser71-workarea-overrides to add the following style.

.repeatTabbed UL LI {
  height: auto;

A bug item has been reported for this too (BUG-186407).
