@srnitish can post here ?

Hi all I am working on this website (https://kokorikko.com) I did everything specified and still have no result :/ do you have any idea ?
PS: I am using Motion Theme

dear Jonathan Moore,

I am working with paid prestige theme and want to use hide unavailable variants, I follow all settings but not able to get a solution would you please guide me to sort out this issue,

thanks

Works for Turbo Portland Theme !

@sughramehdi It's not working for hiding sold-out variants with only one option in the Turbo Portland theme. Can you please tell me which code you used? did you do any changes to the code?

Anyone know how to do this with the Shopify 2.0 Dawn theme?

How do I completely reverse the script? I deleted the created snippet but my sold out / unavailable products are still hidden.

Seconding @sciascia - has anyone figured this out for the Dawn theme?

We updated the gist to work with other themes by allowing you to add the select class to a variable, as well as choose whether sold out variants are hidden or not.

Has anyone found a solution for the following issue?

When having 3 dropdown menus for 3 variant options, I go ahead and change one option and then it says "unavailable" even though that variant-combination exists. Then I go ahead and change the variant option and it goes to "available". Then I switch back to the old variant options which showed "unavailable" which now shows as "available".

I use the Debut theme and get the error "Uncaught ReferenceError: $ is not defined" in line 110. Same as @akenger. It was the first issue, but never solved, I think

2 possible solutions:

1. You're trying to use jQuery before it's loaded. In which case you need to move your code to somewhere after it's loaded.
2. Sometimes themes re-use the $ selector, so you need to change your code to explicitly use jQuery instead (i.e. replace $('.selector') with jQuery('.selector')

Hope that helps.

Has anyone been successful with getting this to work on the dawn theme?

the issue is that the script triggers jquery events, and the jquery events are NOT listened to by vanilla javascript events. As a result, the cart does not update correctly

change this line

https://gist.github.com/jonathanmoore/c0e0e503aa732bf1c05b7a7be4230c61#file-gistfile1-html-L63

and this line

https://gist.github.com/jonathanmoore/c0e0e503aa732bf1c05b7a7be4230c61#file-gistfile1-html-L125

to fire this instead
selector[0].dispatchEvent(new Event('change'));

after a quick test, seems to work fine

@PhilipAV to the question the answer is yes. I'm using 3 variations on a responsive theme by out of the sandbox and it works. This solution isn't meant to be an out of the box solution. The author stated that it was made for the District theme. You will have to break it down to see where the issue is arising from. There can be many things that are causing it not to work.

Hi Omar, hope you are doing well!

I am working on a clients Flex theme and saw your comment. I am working through the linked options snippets and console.logging each and every step.

However I was unable to find it.

Since you solved that issue with your out of the sandbox themes would you please tell me if you by any chance solved it on flex?

I would love to learn from you and solve this issue.

wishing you a lovely day, Ramiz

Hello,
Thanks for the script.
For those of you who are having issues with the default variant not loading and requiring the user to select a variant before the script fires:
This is what worked for me on the Shopify Debut Theme.
Find the following code:
Shopify.linkOptionSelectors({{ product | json }});
It is located in the following if statement

{% if product.available and product.options.size > 1 %}
...
Shopify.linkOptionSelectors({{ product | json }});
...
{% endif %}

Simply move it directly outside of the if statement:

{% if product.available and product.options.size > 1 %}
...
// Line removed from here
...
{% endif %}

// Line added here
Shopify.linkOptionSelectors({{ product | json }});

Keep working on Debut ... Thanks

Hi William,

I tried this and it worked on Flex theme (out of the sandbox) with 2 variant dropdowns so far that:

• if you change the first variant dropdown, the second dropdown only has variant options that are available.

However if you select one of the 2. variant options the selected option is not the same as the one that is displayed afterwards. It just changes after you select it.

also it does not work with default value of the 1. variant selection. only if you change the first variant.

Can somebody help me please on that?

It seems such an easy task but became a nightmare for me here :/

Thanks!
Ramiz

Anyone here got this to work with Prestige theme with 7.X.X? I would love to get it to work since i need this badly ;)

@roarsweden This is pretty outdated at this point. With the big shifts with Online Store 2.0 and how themes are structured now I doubt this would work with any theme created or updated in the last two years.

@jonathanmoore any pointers as to a solution that WOULD work with current themes?
