Possible GSAP/ScrollSmoother issues

Recommended Posts

I've got a site nearly ready to go live but I'm having a couple random issues and I can't quite tell if they are purely GSAP-related or just pure JS incompetence.


If someone can take a look and shed some light on which direction for me to take in terms of troubleshooting, I would really appreciate it.


Problem #1:

The menubar layout seems to be messed up on the blog index and blog archive pages, and it won't open. I see that the console is giving me a TypeError but I don't know why it's happening or how to fix it. I can also see that somehow some of the menu divs on those templates aren't in the correct places. The div setup is supposed to be:


[left div] [middle div > logo] [right div > menu overlay divs]


Problem #2:

I've added a Swiper slider to my blog posts. It's conditional and should only appear if the ACF fields I created for it aren't empty. But the page doesn't scroll down all the way. If I inspect the page, it seems to fix itself, but that doesn't help me when I try to troubleshoot.


I'm also seeing several "GSAP target null not found" errors throughout the site and I can't pinpoint where they are.


I'll peruse the Googles for a JS forum to post in as well, since I'm not sure if the error is in my GSAP code or somewhere else.


Thanks in advance!

Unfortunately we really can't troubleshoot lives sites effectively. 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

See the Pen aYYOdN by GreenSock (@GreenSock) on CodePen


If you're using something like React/Next/Nuxt/Gatsby or some other framework, you may find CodeSandbox easier to use. 


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