 # How-to-display-multiple-members-in-WinForms-MultiColumnComboBox
-This sample shows how to display multiple members in WinForms MultiColumnComboBox.
+The multicolumn combo box is an advanced combo box control that has the capability of showing multiple columns in the drop-down list.
+
+## Core Feature
+Built by combining the combo box base with Syncfusion Grid control, this multicolumn combo box provides a very rich combo drop-down option for your forms. Also, since the drop-down list is bound virtually to the data source, data binding to a very large data source is instantaneous.
+
+## Custom Flitering
+The multi-column combo box populates list values based on filtering criteria.
+
+By custom filtering, items can be filtered by comparing all the columns or specific columns using predicate filter options.
