How to output child taxonomy in WordPress?

Hi,

I have a taxonomy called Product Categories like so:

How would I go about listing the children of say Boxing that are in use (ticked)?

For example, say I wanted to output Boxing’s child which is Boxing Headgear?

Thanks in advance.

Got it.

In case anybody else need the solution:

wp_list_categories('title_li=&taxonomy=product_cat&hierarchical=1&child_of=17');
