Reply To: how to position a custom hook where i want it?

Ignore what I said above – not sure what I was thinking.

A much better way of doing this is explained here: http://generatepress.com/forums/topic/formatting-text-in-header/#post-108188

As of right now, there’s no way to add anything else in the mobile menu.

However, I just made an adjustment so that you can insert something into the mobile menu in version 1.2.9.7.

You could do something like this:

add_action( 'generate_inside_mobile_menu', 'generate_add_mobile_menu_content' );
function generate_add_mobile_menu_content()
{
	echo '<span class="mobile-content"><a href="tel:123-4567">Call me</a></span>';
}

Then you could float that to the left:

.mobile-content {
      float: left;
}

Again, this won’t work until GP 1.2.9.7.
