menu

Hello all,

I am reading those interesting questions, and i am learning a lot
from them!
Now i have a question. Hope i can explain myself in englisch.

How can you make a button, when you click on it, there come 3
clickable items underneath it. (or any ammount i want, depends on how
much pages i have).

I have an example underneath here.
In this example i have clicked on “Kozijnen” which is a page, and 3
other menu’s appear, 3 other more pages.

Hope you can make this in freeway.

Marianne
