Toxonomy is being used to group content with the same tags. If you want to show these tags, you can make a view and present it as a block or page.
The taxonomy menu module does the same but better...E.g. It is able to respect the hierachy of the terms.
First i make some terms..
After activation of the module, you find with structure the configuration. Add a menu.
You choose the vocabulary and adds them to an existing menu. I have created a new menu for that purpose: Tax Menu.
As always, a block has been made to put the menu on the screen.
You can configure the block even more...
In combination with the superfish module, more configurations are possible.
