I don't understand what you are trying to do exactly, are you trying to freeze or pin a column that is wider and outside of the viewport? If that is the case you should get an error in the console saying that you cannot and if so that is the expected behavior. So please check your console and see if any errors are displayed, I remember creating this PR in SlickGrid core lib to block user from expanding the column outside of the visible viewport (which is not permitted because then all columns become hidden under an invisible div)

I also cannot provide any help without a way to reproduce the error. I also will not provide support for columns that are outside of the viewport because it's simply too hard to fix

Yes, that's what i want achieve. And there is error in console. It will be any possibility to change this behavior that left viewport horizontal scroll will be usefull? I mean when freeze column that is outside of the viewport let user scroll right or left. I think it will be much user friendly than console error

That is not the typical approach, users don't like to see multiple scrollbar that does the same thing. You can add CSS to also show scrollbar of the left viewport yourself if that is what you want. We will not add any grid option for this. Also if you don't want the error, you can always add a try/catch and do nothing when catching the error, if you also add CSS for the scrollbar, then that should go you what you're looking for but that is not something that we will do in this lib. You could maybe try this Stack Overflow answer to show the scrollbar on the left

The error that you see comes from SlickGrid when you indeed try to expand freeze columns that are outside the viewport, this error was brought in this SlickGrid PR and the reason you cannot expand the Title column more than the viewport is because of this SlickGrid PR.

I'm closing this issue since you barely provided any reproduction and you seem to be having problem with freezing columns outside of the viewport which I already said is not, and will not, be supported by SlickGrid... so closing
