Hello !
I’m using webix.ui.multiselect component.
I need to disable (grey out) some of the values.
I was able to achieve that by:
list.disableItem(itemId)
It indeed greys out the value and when I hover over that item → I can clearly see that browser cursor is suggesting that element is disabled
However… I can still select it when I click on it…
Is it some kind of known bug ?
Ok, I figured out that I need to use suggestbox
Then it is not possible to click on disabled element.
Still… I think it might be a bug, it does not make much sense to have ability to click on disabled element 
But maybe I just missed something in docs.
Thank you !
