Menu does not expand

Hello,

I have a problem with my meniu as it does not expand (please screenshop).

Could you please let me know how can i fix it?

You'll need to start by giving us some more info about how the menu is made.
Do you have a link to the website?

Having heard nothing back, I'm guessing you solved your problem.
Anyway, if not, you could try adding this to your css, but not knowing your problem that could be useless.

.mod_navigation {
overflow: visible;
}

SOrry for not replying for so long. Exactly we solved the issue. Thank you for your advice.
