A component that lets you pick values from a dropdown grid with multiple columns.
Supports data binding and server-side loading via OnRead, configurable popup settings through MultiColumnComboBoxSettings, column definitions with MultiColumnComboBoxColumns, custom row rendering via RowTemplate, prefix/suffix content and separators, open/close events, and list sizing with ListHeight. When using virtualization, requires ListHeight and ItemHeight, and does not support grouping.
Children: MultiColumnComboBoxColumns, MultiColumnComboBoxSettings, MultiColumnComboBoxPrefixTemplate, MultiColumnComboBoxSuffixTemplate.
