Multicolumn feature doesn't work for me

Now I can see it. A cache issue. Have you the cache activated on your website ??
I see the issue, the problem is that the ja-purity is very complex and has its own dropdown menu css which are not compatible with the one of maximenu.
Try a default maximenu theme to see if it works

In the plugins the "System-Cache" is turned off ...

But in the Tools > Clear Cache I found MaxiMenuCK cache or something like this.
So I cleared this from cache.

Default CSS module of MaximenuCK is working, but "not nice"
The long menu-titles are flowing out of the fixed-height "boxes" and are covering each other.

See for example the following menus:
Felszín alatti víz > Kézi vízszintmérő műszerek
Felszíni Víz > Mélység-integráló víz- és lebegtetett hordalék mintavevők
etc.

But also every other menus which are longer than 1 row, are "ugly"

Can the height of the menu "boxes" set to automatic depending from its content?

yes what happen now is that the theme set a height for the elements and as yours are very long they overflow on multiple line.
to fix this, go in the maximenuH_CK.PHP file located in the module and change the height properties to min-height :
Line 41 :


Line 128 :
and this should work

Now its working! It is what I wanted!

THANK YOU FOR YOUR HELP!!!

(One more question: shall I keep ja-sosdmenu.css keep as modified, or can I recover it to its original state?)

Sorry for wasting your time, but I have one more problem:

if you select the multicolumn parent menu-page, or when you select a child menu-page of the multicolumn parent menu like for example:

Felszíni víz > Mélység-integráló víz- és lebegtetett hordalék mintavevők > US DH-48 mélységintegráló lebegtetett hordalék / lebegőanyag mintavevő
[url=http://http://vizszintmero.hu/melyseg-integralo-mintavevok/us-dh-48-melysegintegralo-lebegtetett-hordalek-lebegoanyag-mintavevo] vizszintmero.hu/melyseg-integralo-mintav...ebegoanyag-mintavevo [/url]

then you can see in the "breadcrumb" the menu-path of this page.
Unfortunatelly also the parameter [cols2] is shown ...
Why is it shown? How to hide this [cols2] parameter in breadcrumb?
