[TYPO3] disable context menu

[Bas Heutink]

Hi list,

I am customizing the backend by disabling options.
Only thing I can not disable is the context menu.

I entered this TS in the TSconfig of the usergroup:
folderList.disableIconLinkToContextmenu = 1
pageList.disableIconLinkToContextmenu = 1
pageTree.disableIconLinkToContextmenu = 1

But the context menu will not disappear.
Any suggestions?

Regards,
Bas
