# Model Check - Classification Status

Class Feeder enables effective element classification status checking. Elements in the selection by category and instance selection are marked by color according to their classification status:

* ![](/files/IKueFCMvmwup2VLbANoy) Category/instance classification state is not checked
* ![](/files/1wjUZ5jNElHUCcLl9TOP) Category/instance is classified in all selected facets
* ![](/files/A26sExuOeWpXjZchVnOz) Category/instance is not classified in all selected facets

The user selects facets to be checked using the buttons above the category selection area. Any combination of facets is possible. When multiple facets are selected, the elements are marked green only if they are classified in all selected facets.

For better clarity of the classification status, it is possible to switch off all already classified elements so that only those that still need to be classified in the selected facets are displayed. The user can do this by using the checkbox for hiding classified elements - checkbox with green color. Conversely, unchecking the checkbox with red color will hide all elements and categories that are not classified.
