[Question] Disabled NavigationRail

[ingdesarr1]

Question

Good afternoon. In the moment I'm using a NavigationRail, and in this point, I want to disabled to prevent the user exit or change the page by mistake. If I consult the properties of the NavRail, disabled appears, not in the documentation, but yes in the editor. If I put disabled in True or False, don't do nothing. Is a mistake of the code or mine?

Thanks
