The MultiColumnComboBox allows you to predefine the columns that will be rendered in its drop-down list through the dropDownWidth option.

The columns also allow you to set their columns.width.

  • If the widths of all columns are defined in pixels through their width option, the dropDownWidth value (if set) is overridden.
  • In all other cases when the widths of all columns are not set, the dropDownWidth value is applied to the element.

You can also define which dataItem field will be populated and also set a title, a template, and a headerTemplate.

        .Columns(columns =>
            columns.Add().Field("ContactName").Title("Contact Name").Width("200px")
            columns.Add().Field("ContactTitle").Title("Contact Title").Width("200px");
            columns.Add().Field("CompanyName").Title("Company Name").Width("200px");
        .DataSource(source => source
            .Read(read => read.Action("Products_Read", "MultiColumnComboBox"))
