Problem with nav css menu boostrap

Ready buddy ... Corrected. I added some DIV's and changed the CSS a bit. It's missing now just add the ICONS that will stay the same. Understand that the menu items are not centered, in this example you have shown, they are on the left, but with the icons pushing them to the right, it gives this false impression of centralization.

<!-----------   Menu   --------------------->
<div id="sidemenu">
   <div id="menu-header"></div>
<div id="menu-parent">
<ul id="menu-itens">

    <li class="dashboard">
        <div>
        <div class="item-menu-icon"></div>
        <span class="item-menu-title">Dashboard</span>
        </div>    
    </li>

    <li class="lojistas">
        <div>
        <div class="item-menu-icon"></div>
        <span class="item-menu-title">Lojistas</span>
        </div>    
    </li>
    <li class="usuarios">
        <div>
        <div  id="item-menu-icon" class="glyphicon glyphicon-user"></div>
        <span class="item-menu-title">Usuarios</span>
        <div>
    </li>
    <li class="notificacao">
        <div>
        <div class="item-menu-icon"></div>
        <span class="item-menu-title">Notificacoes</span>
        </div>
    </li>
    <li class="relatorio">
        <div>
        <div id="item-menu-icon" class="glyphicon glyphicon-signal"></div>
        <span class="item-menu-title">Relatorios</span>
        </div>
    </li>
</ul>
