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

Getting Started

You can set which field from the dataItem will be populated by defining a title, template, headerTemplate, and width.

        .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"))

Setting Column Widths

The MultiColumnComboBox allows you to set the width of the drop-down through its 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.
