Hi,

Thank you for this idea. We will track the demand here, and possibly include this enhancement in our future plans based on the interest and perceived business value.

Meanwhile, I can suggest checking out our documentation article on creating a custom reusable filtering component that features a sample multi checkbox filtering component:

https://www.telerik.com/kendo-angular-ui/components/grid/filtering/reusable-filter/#toc-multi-checkbox-menu-filtering

Developers can use the component from our demo, or create a customized one similar to it, and customized for their specific needs.

Regards,
