Sub pages

Hi, I was able to create a menu with the corresponding sub-pages. The name of the page would be, for example, “animals” and the sub-pages would be “cow” and “sheep”. Is there any way that when the user clicks on “animals” nothing happens? I want to force the user to click on either “cow” and “sheep”. Right now, if the user clicks on “animals” then it takes the user to that specific page, but I don’t want to add anything under animals. Hope this makes sense, thanks!
