Class: Mechanize::Form::MultiSelectList

This class represents a select list where multiple values can be selected. MultiSelectList#value= accepts an array, and those values are used as values for the select list. For example, to select multiple values, simply do this:

 list.value = ['one', 'two']

Single values are still supported, so these two are the same:

 list.value = ['one']
 list.value = 'one'
