Hi Jose,
If the accessibility is a must in your application, please use filter row instead of filtering using the column menu.
The column menu is not intended to replace the filter row or any other configuration. It is additional(optional) UI, that is based on user customisable templates. It is called menu, but it is actually context popup, and not real menu (as it includes inner components, and not just options to choose from).
Regards,
Vasil
