Scrolling to anchor links

I created an anchor link on one of my pages.  It refreshes the page and goes to the correct anchor link position.  How do I tell the site to just scroll to the anchor link position and not refresh the page to the location?  

I am missing some custom code or settings?

Are you using just the anchor link or the entire URL plus anchor link?

@Ziggy I tried both, just putting the anchor #id after the page slug and the entire domain.  

If this is contained on one page, then just use the ID without slug or domain, i.e. #spa

@Ziggy I see.  The only issue now is it does not scroll down to the part on the page, it just jumps to the location.  Is there something I need to add to have it scroll down to the location?

@Ziggy any ideas?  thanks
