sub menu's not staying open, parent link & other options are ignored

[xtracold]

I am trying to extend our wordpress theme to include submenu's (under products). But whenever I add submenu's through the wordpress menu widget, slicknav picks it up but then behaves eratically showing/hiding the menu. Check out www.unifire.ca for the behaviour. When expanding products it will then hide the menu before you have a chance to select. In some cases you then cannot click and have the menu show long enough to select something. I have modified and tried all I can think of in the javascript options and css but no luck getting some semblence of control over the menu.

Would appreciate any guidance you can give me on this. Right now i'm considering removing the slicknav menu and using an alternate. I've inherited this code / implementation from our previous developer but they are no longer able to provide support.
