@McDracostar link is not working and it would be very hard for me to fix anything from github without an context

Hi @marioloncarek , apologies, what I mean is the code I found, seems to duplicate the search bar from the standard navigation bar, to the sticky so it can remain functional.
(image attached)

In saying that do you know if (and how) the code seen in my previous comment can be duplicated and modified, to do the same for the go-cart?

Also sorry somehow it linked your own name this link should work now https://we.tl/t-weKtNZInjz

as i said, goCart already searches for cart classes, your goCart script tag is probably before the core js script tag, it should be the other way around @McDracostar

Hi @marioloncarek , if you meant where in the theme file it is implemented it is placed afterwards near the bottom of the theme.liquid file
If you mean the following:

{{ 'gocart.js' | asset_url | script_tag | async }}
<script>
var goCart = new GoCart();
</script>

Then yes this is placed just before the < /body > closing tag as goCart requires. And the Theme.js script is up the top within the < head >tags

@McDracostar and the cloned cart is not opening, right?

@marioloncarek , yeah~ that is correct, the cloned cart won't open, and I think its because the core theme.js isn't duplicating the cart correctly.

But I think the snippet of code I showed you earlier might explain why the search function still works fine, because it is duplicating the functions from my understanding.

@McDracostar check if gocart class gets cloned

also try to remove async/defer from both tags and see if maybe this is causing the problem

@McDracostar check if gocart class gets cloned

@marioloncarek , can confirm the class is cloned yes. and I removed the defer from the theme.js tag, and the async from the gocart.js tag.

1. First tested the removal of defer from the theme.js and the stickynav stopped working.
2. Along with that, I then the removed async from gocart so both no longer have them, the go-cart continued to work, but the stickynav still wouldn't show.
3. So I restored the codes back to how they were after that, trying a combination of one without the other and even changing from defer to async and visa vie.
   

sorry bro all i can do from this position

All good man! Thankyou anyway, I appreciate your assistance.

@marioloncarek Hope you are doing well mate I have integrated go cart in my theme but it is not triggering with Add to Cart button using debut theme

Here on the product page it is not triggering. integration done on debut theme. And also the cart is not updating in real time have to refresh again.

@marioloncarek code is very nice and working fine, Just need one assistance that price is skipping decimal value

If price is 62.99 it is showing 6299
