Parent-Child Page Relationship Question

Up front:
•I’m a WordPress rookie
•Can’t find the answer to this question in the Codex
•I’m using the default Twenty Fourteen template

I have seven Pages set up on my site, the names of which appear horizontally across the top of the page in a menu. That’s all good.

One of the Pages is a Parent page with four Child pages. Putting the cursor over that Parent Page title in the menu produces a drop-down menu showing titled links to the four Child pages. Again, all good.

There is no content on that Parent page. It serves only as the heading title for the four Child pages beneath. But if you click on the Parent title in the menu, it takes you to a blank page. Probably few people will click on the Parent title — they will click on the Child title they want to go to. But if someone does click on the Parent title, a blank page appears.

QUESTION: Is there a way to keep an actual blank page from appearing if someone clicks on the Parent title link? That is, I would like it to do nothing but reveal the drop-down menu with the four Child pages.

If it helps: the site is basileiaproductions.com and the Parent title in question is SERVICES with four Child pages beneath. I’d like for nothing to appear if someone clicks on SERVICES.

Thanks for any suggestions,

WK
