Note that default values are not supported for multi-level selects. For example "Country,City" could be valid values. The columns that should represent levels must be specified in the value field. If United States was chosen first, then San Francisco and Chicago would be options, but if Mexico was selected then instead Mexico City and Cancun would be options. After the user selects a country, a "City" drop down would appear. This would result in a first drop down with the options "Select a country.", "United States", and "Mexico" (the initial selection is "Select a country.", which serves as a label for the drop down). For example, to have a 2 level selection where you first select a country and then a city, you could specify a file such as the following: The property file is a tab delimited file, with levels defined in columns and choices defined in rows.
