Question

The icone is not aligned with the text

Good follows the code of the menu, I already thank the help.

$(".top_menu ul").each(function() {
  alignMenu(this);
  var robj = this;
  $(window).resize(function() {
    $(robj).append($($($(robj).children("li.hideshow")).children("ul")).html());
    $(robj).children("li.hideshow").remove();
    alignMenu(robj);
  });

  function alignMenu(obj) {
    var w = 0;
    var mw = $(obj).width() - 150;
    var i = -1;
    var menuhtml = '';
    jQuery.each($(obj).children(), function() {
      i++;
      w += $(this).outerWidth(true);
      if (mw < w) {
        menuhtml += $('<div>').append($(this).clone()).html();
        $(this).remove();
      }
    });
    $(obj).append('<li class="hideshow">MAIS&nbsp;&nbsp;<i class="material-icons">keyboard_arrow_down</i><ul>' + menuhtml + '</ul></li>');
    $(obj).children("li.hideshow ul").css("top", $(obj).children("li.hideshow").outerHeight(true) + "px");

    // Abre o menu
    $(obj).children("li.hideshow").click(function() {
      $(this).find("ul").animate({
        height: 'toggle'
      }, 'fast');
    });
  }
});
$(".top_menu ul li").click(function() {

  // Verifica se tem link
  if (typeof $(this).data('link') !== 'undefined') {
    //document.location.href = $(this).data('link');
    console.log('link ok');
  }
});

.material-icons {

  overflow: hidden;
  vertical-align: middle;
  font-size: 24px;
}

.top_menu {
  width: 100%;
  background: #616161;
}

ul.horizontal-menu,
.horizontal-menu ul {
  list-style-type: none;
  margin: 0;
  padding: 0;
}

.horizontal-menu {

  width: 100%;

Answer 1

Add to class .search-icon at first li of ul

<ul>
    <li class="search-icon"><i class="material-icons">search</i></li>
    <li data-link="http://www.google.com">MENU 1</li>
    <li data-link="http://www.google.com">MENU 2</li>
    <li data-link="http://www.google.com">MENU 3</li>
    <li data-link="http://www.google.com">MENU 4</li>
    <li data-link="http://www.google.com">MENU 5</li>
    <li data-link="http://www.google.com">MENU 6</li>
    <li data-link="http://www.google.com">MENU 7</li>
    <li data-link="http://www.google.com">MENU 8</li>
    <li data-link="http://www.google.com">MENU 9</li>
    <li data-link="http://www.google.com">MENU 10</li>
    <li data-link="http://www.google.com">MENU 11</li>
    <li data-link="http://www.google.com">MENU 12</li>
    <li data-link="http://www.google.com">MENU 13</li>
    <li data-link="http://www.google.com">MENU 14</li>
</ul>

Then add to your css.

.search-icon {
    padding: 22px;
}

If that’s what I understand try to do the following:

<div class="top-fundo">
   <div class="container">
      <ul> ... </ul>
   </div>
</div>

in css:

.container {
  width: 960px; /*defina o width*/
  margin: 0 auto;
}

I hope I’ve helped.
