javascript - 限制 div 中的文本，但使整个 div 可点击

Question

我有这个 styled-select 是我根据自己的要求制作的。现在的问题是，如果选中的选项大于整个区域，自然会填满整个div，如下图所示:

现在我希望它被限制或者右边有一个边距，以便显示我用作background: url的箭头，如下图:

如果我减小 div 的宽度就可以了，但问题是它无法点击以打开下拉菜单。现在我想知道是否有解决方案来限制文本但仍然有可点击区域？

这是我的代码: Working jsFiddle

$(function() {

   $('.styled-select select').hide();
   $("select#elem").val('0');

   $('.styled-select div').each(function() {
     var $container = $(this).closest('.styled-select');
     $(this).html($container.find('select option:selected').text());
   });

   $('.styled-select div').click(function() {
     var $container = $(this).closest('.styled-select');
     var opLen = $container.find('select').children('option').length;
     if (opLen < 5) {
       $container.find('select').show().attr('size', opLen).focus();
     } else {
       $container.find('select').show().attr('size', 5).focus();
     }
   });

   $('.styled-select select').click(function() {
     var $container = $(this).closest('.styled-select');
     var text = $container.find('select option:selected').text();
     $container.find('div').html(text);
     $container.find('select').hide();
   });

   $('.styled-select select').focusout(function() {
     var $container = $(this).closest('.styled-select');
     $container.find('select').hide();
   });

 });
