navigation drop down browser problems

Hi Ray

On this site http://bit.ly/2PQpzC2 if you hover over 'Event Info' you get a drop down sub menu which works fine in Firefox, Chrome and IE but in Edge the <ul> and <li> styling that makes up the navigation isnt being applied as you can see here: http://prntscr.com/kx4rl4 the bullets are visible and when you actually go to click on one of the sub nav elements, the drop down disappears and you're not able to click on any.

I cannot see what is causing this at all. Apparently there is also a problem in Safari but I dont have it so I cannot say if its the same problem or something similar.....

Any help / advice greatly appreciated

Cheers

Jamie

It appears it may be a jquery issue. Have you tried updating to the latest jquery version? It looks like your page has several jquery versions loaded on the page. I'd remove all but one and try a newer version. You have several instances of 1.8.1 and 2.1.3 listed on the page.

I'd clean that up to have only one version of jquery and try using version 3.3.1.

This is something I'd really need to spend some time debugging to fix, but I'd probably start there.

Maybe add just the menu to a blank page with just one jquery version to see if the latest fixes the problem.
