Hello Manuel,

We dont have any property exposed for that but using the CSS you can do . We have class property exposed on the control .

something like this :

<style>

    .Classname
    {
    /*  display: none;
      visibility: hidden;*/

    opacity: 0.6;
    pointer-events: none;
    }

</style>

    <div class="container vertical">
        <div class="container vertical">
            @if (CountryData != null)
            {
                <IgbMultiColumnComboBox Height="50px" Width="400px"
                    DataSource="CountryData"
                    Fields="DisplayFields"
                    TextField="Country"
                    Placeholder="Choose a country"
                    DefaultColumnWidth="200" contenteditable
                    Class="Classname" />
            }
        </div>
    </div>
