Menu and childs

I use the theme Parabola and really like this theme and now I wonder if there is any way to make the childs not appear under the menus, so that you instead click on quests (I making a site for a game), you then will be taken to the quest page and there you can click on whatever order the quests are placed in. Like now I use the a, b, c, d and so on system and it be a long drop down and then next a long drop down when they hover with the mouse over let’s say b. I really hope its is possible to in some way hide this on some menus, not all.
