I wanted to add an external link button to the menu and so I've created a custom menu using the following in my child theme. 'Store' is the external link. You can have a look here at http://www.crossbirdproject.com.
<?php
function childtheme_menu() { ?>
<div id="menu-primary" class="menu">
<ul class="sf-menu sf-js-enabled">
<li class="<?php if ( is_page('home') ) { ?>current_page_item<?php } else { ?>page_item<?php } ?>">/">Home
<li class="<?php if ( is_page('products') ) { ?>current_page_item<?php } else { ?>page_item<?php } ?>">/products" >Products
<li class="<?php if ( is_page('blog') ) { ?>current_page_item<?php } else { ?>page_item<?php } ?>">/blog">Blog
<li class="<?php if ( is_page('about') ) { ?>current_page_item<?php } else { ?>page_item<?php } ?>">/about">About
<li class="<?php if ( is_page('store') ) { ?>current_page_item<?php } else { ?>page_item<?php } ?>"><span>Store</span>
</div>
<?php }
add_action( 'wp_page_menu', 'childtheme_menu' );
Now this is all fine and looking good except now my drop down menu under 'Products' isn't working. It was working fine when it's not a custom menu.
I'm new to this so any help is much appreciated!
