How to hide menu item in mobile

I have the "Mobile Menu CK pro" and i try to hide a menu item in mobile only.
I thought that the otpion "Enable for mobile" in the tab "Mobile Menu CK" is doing this, but it doesn't work in my site...
Please do you have any idea about this?
The website is www.rousis.gr

Hi
I have checked your request

I thought that the otpion "Enable for mobile" in the tab "Mobile Menu CK" is doing this

>> yes this is the case, this option is made to hide the item in the mobile menu
But this option only works with the module Maximenu CK ... this information is missing from my doc !

you can stil use some CSS rules to hide your items manually : this will hide the menu item with the ID 1309 (Έργα)

Very good!!!
It works, thank you so much.
By the way the "Maximenu CK" looks interesting!
I will check it.
