Hi Emilio,

Greetings from Syncfusion support.

Yes, it is possible that to filter by Contains in WebAPI adaptor. We have API to filter based on value contains in multiselect.

The FilterType API will let you to use following options,

StartsWith (default)
EndsWith
Contains

If you are not mentioned any type to the above API, it will take default type of filtering as StartsWith

Code example for reference:

EjsMultiSelect TValue="int?[]" FilterType="@Syncfusion.EJ2.Blazor.DropDowns.FilterType.Contains" AllowFiltering="true" Placeholder="Select a name" Query="@RemoteQuery">

<EjsDataManager Url="https://ej2services.syncfusion.com/production/web-services/api/Employees" Adaptor="@Syncfusion.EJ2.Blazor.Adaptors.WebApiAdaptor" CrossDomain=true></EjsDataManager>

<MultiSelectFieldSettings Text="FirstName" Value="EmployeeID"></MultiSelectFieldSettings>

</EjsMultiSelect>
