I want to choose columns by checkboxes, something like this:

Hello, Radek,
Currently, there is no official timeline for when this feature will be added to the RadGridView Column Chooser. I understand your interest in this enhancement, and I have already communicated your request to the team. Your suggestion has been acknowledged as valuable and will be taken into consideration during our next planning. We truly appreciate our customers’ feedback and strive to deliver the most requested features. However, I am unable to provide a specific timeframe for this feature, as we must also prioritize other ongoing initiatives.
What I can suggest is to vote for the item. The more votes an item gathers, the higher its priority become. And also subscribe to it, so you will be notified when its status changes to "'Planned".
