By default, drop down list is filtered based on `SearchCondition.StartsWith` condition. You can change the filtering search condition by setting [SearchCondition](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.Grid.SfMultiColumnDropDownControl.html#Syncfusion_UI_Xaml_Grid_SfMultiColumnDropDownControl_SearchCondition) (StartsWith, Contains, Equals options).
