ForEachOptionTag

public class ForEachOptionTag extends LoopTagSupport
This class is a custom action for creating HTML select lists, checkboxes or radio buttons, where some items need to be marked as selected based on dynamic data. The names and values for the options are provided through a Map, and the selected values are provided as a String[]. The action exposes a bean with three properties to actions in the body, representing the current Map entry:
  • String text
  • String value
  • boolean selected
