Hi Evgeny,
Thanks for contacting Syncfusion Support.
We suggest you to change the filter type as “contains” through filtering event of DropDownList as shown below
We have prepared a sample for reference. Please refer to the below given link
UG : https://ej2.syncfusion.com/angular/documentation/drop-down-list/filtering/#change-the-filter-type
Please let us know if you need any further assistance.
Thanks,
Christo
