creating a drop down box that you aren't able to click the first heading

[flagrags]

Hi

Ok I don't no whether this makes sense, I don't no the techno lingo to describe this properly:

On my homepage I have headings in the header that are drop down boxes when you hover over them. My problem is I don't want the initial heading to be clickable - I just want it to be a heading with a drop down box where you can click on the product you want i.e.

Shop (initial heading, not able to click, just when the mouse hovers over the word the drop down appears)

Dresses (drop down, able to click to page)

If anyone gets what I mean, could you please help - I have looked at other prestashop websites that have done what I want.

Thanks
Sam
