Hi Arulraj,
Thanks for the quick update and request for more information.
Yes, a boolean property to allow control over any non-user generated QAT entry in the 'Choose commands from' dropdown would be appreciated. All I see at present is the 'QuickItems' entry, but other items may be possible now or in the future. So, may be a separate boolean property is required for each Syncfusion generated entry in case some are required to be displayed.
A description such as the following may be more accurate:
"A Boolean property to show or hide the default 'Choose commands from' dropdown items in the RibbonControlAdv QAT dialog."
This could be for runtime or designer use.
Regards
Jeremy
