C1ComboBox can be used as an editable text input control with auto-suggest feature that matches the typed text to the list of items. By default, the ComboBox control is non-editable. However, you can make it editable using the [IsEditable](/componentone/api/blazor/online-blazor/dotnet-api/C1.Blazor.Input/C1.Blazor.Input.C1DropDown.IsEditable.html) property. This is a Boolean property which allows the users to modify their input by enabling/disabling editing in the ComboBox control.

To make the ComboBox editable, use the following code. The following example uses the example created in the [Quick Start](/componentone/docs/blazor/online-blazor/controls/input-controls/combobox/combobox-quick-start) section.

```razor
@using C1.Blazor.Input
<C1ComboBox ItemsSource="countries" T="Country" IsEditable="true" Text="Select a Country" />
@code
{
    IEnumerable<Country> countries;
    protected override void OnInitialized()
    {
        countries = Country.GetCountries();
    }
}
```
