How to create a non clickable menu?

Hi,

My problem is simple.
My WordPress menu has 4 entries.
Each entry is a page except the last one which I want to be a drop down menu that gives access to 2 different pages.
I didn’t know how to create such an entry so I created a post category for that purpose.
Then I added that category to the menu.
And finally I added the 2 given pages to the menu, but both as sub-items of the category entry menu.
It works. There’s only one thing that I don’t want: the category entry is clickable. And it lands to a blank page as I didn’t create any post. I only want it to be a menu entry that gives access to my 2 pages, I don’t want it to be clickable.
I hope it is clear.
I followed few tutorials about creating menu but was not able to figure out how to create this.

Thank you for your help,
