add a class to opened mobile menu

Is it possible to add a class to the opened mobile menu?
<div id="maximenuck179-mobile" class="mobilemaximenuck menu-open" style="...">
Now it just changes the style parameters:
<div id="maximenuck179-mobile" class="mobilemaximenuck" style="position: fixed; overflow: hidden auto; z-index: 100000; top: 0px; left: 0px; width: 100%; height: 100%; display: block; opacity: 1;">

Could this be possible?
Thanks
Thomas

Hi
please give me more infos about your need and what you want to do , because the menu is shown/hidden, not opened/closed

Hi,

just for the status of the mobile menu, like:
class="mobilemaximenuck menu-visible"
class="mobilemaximenuck menu-active"

please tell me what you want to do with the status, for a CSS target, a JS function, ... ? by JS you can directly check the display value

just a little animation on the menu items when the menu is visible

ok I see, thank you for the clarification
I can check that and add it in my code, now the problem is that you are using the old plugin Maximenu Mobile which has been replaced with Mobile Menu CK

if you want to use this one, I can do it in the next version and add a CSS class when the menu opens. I can not add it to the maximenu mobile as it is no more updated

let me know
