This stackoverflow post
http://stackoverflow.com/questions/2384167/check-if-internet-connection-exists-with-javascript
describes various methods to check if you’re online.

For your purposes, you’d likely want to use JS to intercept every click on a link. Within your function that intercepts clicks, you’d use one of the above methods to check if the user is online; if they are navigate to the URL and if they aren’t do some other action.

If you implement this you’ll need to make a decision on checking online status every time a link is clicked (and significantly slowing down the performance of your site) or checking at some random interval and simply setting some variable.

I spent a while playing with this as well. The above post got me halfway there but I wanted it to act exactly like the page in the first post (link needs to be in the submenu’s UL and it needs to be an actual link and not just a heading).

Here’s the code I got. The link is clickable and it applies the current_page_item class to itself if it’s the currently selected page (that way whatever CSS you’re using for indicating the currently selected page will extend to this).

I’m note sure how to insert the ampersand without them getting formatted so you’ll need to go through this code block and change them over if you’re just cutting and pasting

<?php
if($post->post_parent){
 $id = $post->post_parent;
 $parent_title = get_the_title($post->post_parent);
 $parent_link = get_permalink($id);
 $children = wp_list_pages("title_li=&amp;child_of=".$post->post_parent."&amp;echo=0");
 $cls = "";
}else{
 $id = $post->ID;
 $parent_link = get_permalink($id);
 $parent_title = get_the_title($post->ID);
 $children = wp_list_pages("title_li=$child_of=".$post->ID."$echo=0");
 $cls = "current_page_item";
					}

if ($children) { ?>
 <ul>
  <li class="<?php echo $cls ?>">
   <a href="<?php echo $parent_link ?>"><?php echo $parent_title; ?></a>
 </li>
 <?php echo $children; ?>
 </ul>
<?php } ?>
