Expand All/ Collapse All does not reflect on child group toggle buttons

[Kanchana]

Hi,
I have a Toggle Button on the header of the parent group (Group Name in example) which when I expand does not reflect on the toggle buttons of the child (BZ Liquor Eat In etc in the example). Same with the toggle button on Department and its sub group toggle buttons. I have attached screen shots for better understanding. 
They all work fine individually, just that when I expand / collapse all, the individual buttons need to change as well. Any help would be appreciated. Thank you

Was there no answer on this? I am also experiencing this same issue.

Hello Eric,

The Expand/collapse All forum thread gives hints on expanding/collapsing multiple parent and child groups/items with a single click.
