How to hide sub-menu item when sidebar collapse, but show sub-menu item when sidebar expands?

Question

Hi, I am trying to hide 'User' item when sidebar closes, but show 'User' again when I expand sidebar by clicking 'Administrator'

I tried using 'OnOpen' attribute for MenuEvents to set 'Cancel = true' for the sub-menu item 'User' when sidebar closes. However, 'Cancel' never changes back to 'false' to show 'User' when sidebar opens. How to fix this? Thanks.

Hi Kenney, 
 
We have checked your reported query. We would like to let you know that when there is single level menu in sidebar, the submenu is not visible after the hidden property is set to false. We have already considered this as an issue in our end. We will include this fix in our upcoming patch release which will be scheduled on March 9th, 2021 and we appreciate your patience until then.
