Category Menü - How to design

[webbie65]

Hello, i want my cateories shown as following:

First i have 4 categories. When i cklick one, i want the others shown under it, so second level (in a menü)
should be horizontal under the first level. But for me it seems, that there are no lists or something in the
menü, at which i could style it with css. Is that right?

It's a normal HTML list which you can style with css.

at my template i have only div -containers.
Maybe, it is, because it is responsive, so
every container is one category and width 25%,
so it will be smaller in mobile view.

Is there any chance to change it or is there any tutorial for it maybe?

you can write a override for your module
