Optional. Use the DxComboBox‘s InputCssClass to customize input box appearance.
Optional. Set the DxComboBox.AllowUserInput to true.
Optional. Use the SearchMode property to enable search mode.
Optional. Use the NullText property to display the prompt text in the edit box when the editor’s Value is null.

<DxComboBox Data="@Cities"
            @bind-Value="@CurrentCity"
            AllowUserInput="true"
            SearchMode="ListSearchMode.AutoSearch"
            SearchFilterCondition="ListSearchFilterCondition.StartsWith"
            NullText="Select City ..."
            ClearButtonDisplayMode="DataEditorClearButtonDisplayMode.Auto">
    <EditBoxDisplayTemplate>
        @if (context != null) {
            <span style="white-space: pre;">Selected City: </span>
        }
        <DxInputBox/>
