problem with drop down menu on mobiles

[vmax]

hi guys
in middle of setting up new site, have changed quite a lot of colours ect in style sheet and all looked great on the pc, however i have just checked the mobile side of things and my drop down menu no longer drops down it simply covers over half the screen hiding the mai content of the site, have spent last 2 hours trying to find the problem but am pulling my hair out
can someone help please, i'm using the responsive classic template

Why are you loading two versions of jquery?

this one belongs there

<script src="https://code.jquery.com/jquery-3.7.1.min.js" integrity="sha256-/JqT3SQfawRcv/BIHPThkBvs0OEvtFFmqPF/lYI/Cxo=" crossorigin="anonymous"></script>
