Hello Aleksandr,

A possible approach is described in the Knowledge Base article linked below:

- https://docs.telerik.com/kendo-ui/knowledge-base/treelist-filter-checkboxes

Another possibility is to enable the columnMenu and set the filterable option to multi: 

           filterable: {
              multi: true,
              search: true
            },            
            reorderable: true,
            sortable: true,
            columnMenu: true,

Here is such a Dojo example: - https://dojo.telerik.com/@NeliK/iwEneWaw
