Tremont redirect Index page navigation URL

Site URL: http://sepia-sheep-3c87.squarespace.com

I'm looking to redirect to regular page or external link, instead of the sub page.

How can i change this code with Custom CSS or something:

<div class="collection-nav-item" data-url-id="the-lingo">
  <a href="/the-lingo" class="the-lingo">
    <span class="collection-nav-item-span">The Lingo</span>
  </a>
</div>

pass: 12345

You can use jQuery to do this. Do you use Personal or Business Plan?

@tuanphan

I will be on business plan.

I changed my mind, I'd like to keep the subpage scroll up feature, so I now longer need to redirect. 

Now I just wanted to have something different. .. AFTER a subpage scrolls to the bottom,  instead of it returning to the "subpage" link of the index navigation I want it to return to the Top (Home) branch of the index navigation.

I have slideshow set up as "animation", and it only works we the Home (top branch) of the navigation is "ACTIVE", otherwise if any other link in the navigation is selected the slide animation does not move once you return back to the index page from a subpage.

I sent you this info directly in an email.

Thanks,
