Add newlines to theme_item_list
I wanted to display Who's Online block as an inline, comma separated list using css.
theme_item_list generates markup like this:
<ul><li></li><li></li></ul>A browser quirk means that due to the lack of whitespace, it won't wrap if you use
display: inline;.
But if you have markup like this it wraps fine:
<ul>
<li></li>
<li></li>
</ul>To add the new line, you'll need to override theme_item_list in your theme's template.php file, then change:
$output .= '<li'. drupal_attributes($attributes) .'>'. $data .'</li>';to
$output .= '<li'. drupal_attributes($attributes) .'>'. $data .'</li>' ."\n";You'll then see the line breaks in your generated html, inline lists will wrap, and all will be right in the world once more.
