I found myself needing the same thing here...
I added the following code from the EZ-Pages Separator, since its going to be the same thing.
<?php echo ($i < $n ? EZPAGES_SEPARATOR_HEADER : '') . "\n"; ?>
at line 21 of tpl_modules_categories_tabs.php
which worked perfect. except that I don't know how to stop the loop. (not have the last item have a separator afterwards...)
as of right now, my tpl_modules_categories_tabs.php looks like this:
include(DIR_WS_MODULES . zen_get_module_directory(FILENAME_CATEGORIES_TABS));
?>
<?php if (CATEGORIES_TABS_STATUS == '1' && sizeof($links_list) >= 1) { ?>
<div id="navCatTabsWrapper">
<div id="navCatTabs">
<ul>
<?php for ($i=0, $n=sizeof($links_list); $i<$n; $i++) { ?>
<li><?php echo $links_list[$i];?><?php echo ($i < $n ? EZPAGES_SEPARATOR_HEADER : '') . "\n"; ?></li>
<?php } ?>
</ul>
</div>
</div>
<?php } ?>
any thoughts would be really appreciated.
thanks.
