Prevent to choose one item from list

[ndmsp]

Hi,

I'm currently using your amazing plugin for a personnal project. Thanks a lot !

I am willing to apply some filters to my list. I achieved to hide the elements from the list, which is correct to prevent the user to select those items with the mouse, but I can't figure out a way to prevent the user to select them with the mouse.

Do you have any idea on how I could disable only few items ?

Thanks a lot,

Regards,

Thomas
