Issue with code causing the page to move up automatically

Hello,
I am new in using webflow, so I would highly appreciate it if someone can help me with the issue that I am facing.
I have implemented custom codes to a page. The custom code is for a drop down menu and a slide bar. When I publish the webpage and select anything from the drop down menu or slide the bar, the whole page automatically moves up and reset all my inputs. Anyone has any idea why this is happening? and how to fix it?

Thank you
