While headers can be made sticky on the MultiColumnComboBox, we're wondering if something similar can be applied to an entire group. In the MultiColumnComboBox dropdown, we'd like the first header and group items to always remain visible while the user scrolls through the remaining groups. If this isn't possible, is there a component similar to the MultiColumnComboBox that could achieve similar results?
With the current implementation, the MultiColumnComboBox component does not include a prop for making the groups sticky. I tried several CSS workarounds and custom rendering, but none of these solutions provided satisfactory results, and the UI became unusable. I also checked other dropdown components in the KendoReact suite, but it seems none of them expose a prop for enabling sticky groups either. Having such functionality out of the box for the MultiColumnComboBox will be beneficial, please let me know in case you would like to see such a property exposed in a future version and I will open a feature request on your behalf.
