Newbie.. any help with a drop down search box!

Hi
We are looking for what seems like simple code.. but need advice from people here. We have a ‘things to do’ page on our website.
What we would like is when the user clicks on that page.. there is a menu box and when hovered/clicked on, it lists all the counties in the uk. When the user selects one.. that takes them to the page we have built on that county.
Is this at all easy to do?
Any help would be fantastic 🙂
