次のコードを使用して、順序付けされていないhtmlリストを選択ドロップダウンリストに変換しています:

jQuery(document).ready( function($) {

//build dropdown - main navigation
$("<select />").appendTo(".region-menu-inner nav");

// Create default option "Go to..."
$("<option />", {
   "selected": "selected",
   "value"   : "",
   "text"    : "Navigate..."
}).appendTo("nav select");  

// Populate dropdowns with the first menu items
$(".region-menu-inner li a").each(function() {
    var el = $(this);
    $("<option />", {
        "value"   : el.attr("href"),
        "text"    : el.text()
    }).appendTo(".region-menu-inner select");
});

//make responsive dropdown menu actually work           
$(".region-menu-inner select").change(function() {
    window.location = $(this).find("option:selected").val();
});

}); 

同時に、Drupal 用の簡易ダイアログ モジュールを使用してモジュラー ウィンドウを作成しています。このモジュールには js ファイルが 1 つだけ付属しています。このモジュールが使用しているコードは次のとおりです。

/*
  @file
  Defines the simple modal behavior
*/

(function ($) {
  /*
    Add the class 'simple-dialog' to open links in a dialog
    You also need to specify 'rev="<selector>"' where the <selector>
    is the unique id of the container to load from the linked page.
    Any additional jquery ui dialog options can be passed through
    the rel tag using the format:
       rel="<option_name1>:<value1>;<option_name2>:<value2>;"
    e.g. <a href="financing/purchasing-options" class="simple-dialog"
          rel="width:900;resizable:false;position:[60,center]"
          rev="content-area" title="Purchasing Options">Link</a>
    NOTE: This method doesn't not bring javascript files over from
    the target page. You will need to make sure your javascript is
    either inline in the html that's being loaded, or in the head tag
    of the page you are on.
    ALSO: Make sure the jquery ui.dialog library has been added to the page
  */
  Drupal.behaviors.simpleDialog = {
    attach: function (context, settings) {
      // Create a container div for the modal if one isn't there already
      if ($("#simple-dialog-container").length == 0) {
        // Add a container to the end of the body tag to hold the dialog
        $('body').append('<div id="simple-dialog-container" style="display:none;"></div>');

                // $() so you have to create a fake div and add the raw data into
                // it then find what you need and clone it. Fun.
                $('#simple-dialog-container').html( $( '<div></div>' ).html( data ).find( '#' + selector ).clone() );
                // Attach any behaviors to the loaded content
                Drupal.attachBehaviors($('#simple-dialog-container'));
              });
              // Open the dialog

  Drupal.simpleDialog.log = function(msg) {
    if (window.console) {
      window.console.log(msg);
    }

  }

})(jQuery);

このモジュールを使用しているリンクは、ソースでは次のようになります。

<a href='/user' name='user-login' id='user-login' class='simple-dialog' title='Login '  rel='width:400;resizable:false;position:[center,60]'>Log in</a>

問題は、そのリンクをクリックすると、ポップアップをロードするのに 1 ~ 2 秒かかり、実際にロードすると、選択ドロップダウン リストの 2 番目のセットが生成されることです。ログイン リンクをもう一度クリックすると、3 番目の選択リストが生成されます。基本的に、ul li から選択リストに変換されたものをすべて複製します。

事前に助けてくれてありがとう。
