    controllers
    Type: nsIControllers
    A controllers list attached to the element. The controllers are used to respond to commands. The document's command dispatcher will locate controllers to handle a command by using the focused element's list.

    Example

    <window id="controller-example" title="Controller Example" onload="init();"
            xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul">
    
    <script>
    function init()
    {
      var list = document.getElementById("theList");
    
      var listController = {
        supportsCommand : function(cmd){ return (cmd == "cmd_delete"); },
        isCommandEnabled : function(cmd){
          if (cmd == "cmd_delete") return (list.selectedItem != null);
          return false;
        },
        doCommand : function(cmd){
          list.removeItemAt(list.selectedIndex);
        },
        onEvent : function(evt){ }
      };
    
      list.controllers.appendController(listController);
    }
    </script>
    
    <listbox id="theList">
      <listitem label="Ocean"/>
      <listitem label="Desert"/>
      <listitem label="Jungle"/>
