Why is nothing inside this div clickable – links and a dropdown

I’m trying to add the Woocommerce Currency Converter and a Login/Register link into a div to the top of my page i’ve made a div and added the widget shortcode but nothing inside the div is working you can’t click the links or the dropdown…

Here is where I placed it…I have tried putting in and out of the header div…its the div called logincur

<div id="wrapper">

  <?php if ( function_exists( 'has_nav_menu') && has_nav_menu( 'top-menu' ) ) { ?>

  <div id="top">
    <div class="col-full">

      <?php wp_nav_menu( array( 'depth'=>6, 'sort_column' => 'menu_order', 'container' => 'ul', 'menu_id' => 'top-nav', 'menu_class' => 'nav fl', 'theme_location' => 'top-menu' ) ); ?>
    </div>
  </div>
  <!-- /#top -->

  <div id="logincur">
    <a href="http://casper-creations.com/my-account/"><b>Login/Register</b></a>
    <?php echo do_shortcode( '[woocs]' );?>
  </div>

  <?php } ?>

  <div class="header">

And the css

#logincur {
	float: right;
	margin-right: 15%;
	overflow: hidden;
}
