QUESTION How to add subtitles to menu?

[cmb]

template.php

PHP Code:

<ul id="nav">
    <?php get_i18n_navigation($slug, $minlevel=0, $maxlevel=0, $show=I18N_SHOW_NORMAL, $component=menu_custom) ?>
</ul> 


Most likely you want to use:

PHP Code:

<ul id="nav">
    <?php get_i18n_navigation($slug, 0, 0, I18N_SHOW_NORMAL, 'menu_custom');?>
</ul> 


Besides saving some keystrokes, this will avoid setting probably undesired global variables.
