Hello Enrico,

If you click the Follow button on this page, you will get an email when this feature gets implemented. The purpose of this page is to let you track that - at the moment an Enabled parameter is not available in the drawer and when it becomes available we will update the documentation: https://docs.telerik.com/blazor-ui/components/drawer/data-bind. I expect that when it gets implemented that will be the exact behavior - there will be an EnabledField parameter of the component so you can point it to a boolean field in your model - and if the value there is false, the item would be grayed out and unclickable.

At the moment, the only way to do that is through a custom template.

Hi Christian,

If the solution I posted would not work for you (a foreach loop in the drawer Tempate plus a few methods that you implement based on our repo once per app), you can consider using a vertical menu in the sidebar - it will have disabled items in our next release.

I agree with you that the components are similar and having that feature would be great in the drawer. It might even make sense for the treeview as well.

Hello Christian,

You can find an example here that, among other things, shows how to get the default rendering of the drawer in its Template so you can customize it: https://github.com/telerik/blazor-ui/tree/master/drawer/template. This can make disabling items easier. I'm also attaching here a modified version of the layout page that shows one way to implement disabled items.

By the way, in the upcoming 2.16.0 release, the Menu will have disabled items binding - you can preview how that would work here.
