Navigation help

Hi,

I’m setting up a site, and am using JointsWP as my base theme. My navigation bar is using anchor points to jump down to each section – however i’ve found that when on mobile, the anchor points work – but the mobile menu doesn’t close once you click a link. PLEASE HELP

Also, is there any way to have navigation items anchor point to a section on one page – but on another page, can they link back to the original page that those sections are on??

The site is here: http://proplumbco.co.uk/home

please help im so stuck!

Thanks
