No ScrollSmoother for another fixed scrollable element

[Fabian W]

Hi guys,

We have a regular ScrollSmoother on the website.

Now we open up a scrollable fixed element ontop.

How to prevent the main page from scrolling while the fixed element is open?

It seems that the scrollable elements scroll is not honored because ScrollSmoother takes over.

How to achieve a second regular scroll element while ScrollSmoother is on?

 

Thanks!

It's pretty tough to troubleshoot without a minimal demo - the issue could be caused by CSS, markup, a third party library, your browser, an external script that's totally unrelated to GSAP, etc. Would you please provide a very simple CodePen or CodeSandbox that demonstrates the issue? 

 

Please don't include your whole project. Just some colored <div> elements and the GSAP code is best (avoid frameworks if possible). See if you can recreate the issue with as few dependancies as possible. If not, incrementally add code bit by bit until it breaks. Usually people solve their own issues during this process! If not, then at least we have a reduced test case which greatly increases your chances of getting a relevant answer.

 

Here's a starter CodePen that loads all the plugins. Just click "fork" at the bottom right and make your minimal demo:

If you're using something like React/Next/Vue/Nuxt or some other framework, you may find StackBlitz easier to use. We have a series of collections with different templates for you to get started on these different frameworks: React/Next/Vue/Nuxt.

 

Once we see an isolated demo, we'll do our best to jump in and help with your GSAP-specific questions.

I updated the topic with a reporduction.

Here is the pen again.

 

It's not possible to scroll the right <aside>.

Hi @Fabian W,

 

Thanks for the extremely simple demo, super easy to solve issues like this 🎉

 

This should do the trick:

ScrollSmoother.create({
  smooth: 1,
  normalizeScroll: {
    allowNestedScroll: true
  }
});

Let us know if you have more questions.

 

Happy Tweening!

Hi again,

 

we are dynamically loading the content now.

NestedScroll is not working anymore,

is it only for content present on the initiation of SmoothScroller?

How to let it recalculate the allowNestedScroll?

 

Edit: on my reproduction with CodePen it works.
Are there any caveats with AllowNestedScroll? 

I cannot find it in the docs.

Best,

Hi,

Honestly I couldn't tell you about that, it seems that this might stem from something else.

 

What you could try is to refresh your ScrollSmoother instance after adding the new content:

const smoother = ScrollSmoother.create({
  smooth: 4,
  normalizeScroll: {
    allowNestedScroll: true
  }
});

/* After Adding New Content to DOM */
smoother.refresh();

That should trigger a full refresh of both ScrollSmoother and the ScrollTrigger instance it uses.

 

Let us know how it goes.

Happy Tweening!
