Hi Sahal,
We have considered to provide this “Excel like Filtering in MultiColumnComboBox” support and logged feature request for the same. We don’t have immediate plan to implement the same and we will implement this feature in any of our upcoming release.
At the planning stage for every release cycle, we review all open features and identify features for implementation based on specific parameters including product vision, technological feasibility, and customer interest. We will let you know when this feature is implemented. We appreciate your patience until then.
We are always trying to make our products better and feature requests like yours are a key part of our product growth efforts.
Regards,
Subburaj Pandian V
