Product Categories widget – how to keep visible?

Hi again, back with a new problem hoping for some help!

I have finally started getting my shop the way I want it to look, but I’m running into one small detail. I set the shop to have a left sidebar column, inside of which I have placed the “product categories” widget.
As it is, this widget creates a select box that when clicked, will open up a list of the product categories I have created. When you click on one, it goes to that categories shop page. This is working as it was intended I believe. My question is, rather than having to click on the select box, is there a way to always have the list of categories visible? It is not obvious as a navigation menu until it’s clicked on.
Any suggestions?
