Instructions:

This is a way to show all tags related to a category, without returning them in a list. This is a great way of adding more SEO, and kill some bounce rate.

Just make sure you change the name of your category where the category_name= starts. Use spaces if your category is named using more than one word.

Put this code where you want the tags to be displayed.
