Here you go,

I did just this the other day, its a bit crafty how it works but it does the job. It only works for a single level of subcategories though

| 
{section name=cat_num loop=$allcategories}

{if $allcategories[cat_num].parentid eq $location[1].1|replace:"home.php?cat=":""}



<font class=CategoriesList>
{ $allcategories[cat_num].category|escape }
</font>|

{/if}

{/section}

This is for V4
