Is it possible to have the options greyed out and disabled instead of hidden?

There's an issue in some themes that the elements won't have loaded in by the time this code runs (even when it's added at the very bottom of theme.liquid). In that case adding a $(function() { ... or equivalent surrounding lines 92-103 may help.

To have the options greyed out & disabled, just remove this piece of code:

else {
  $(this).addClass('soldout').hide().find(':radio').removeAttr('checked').attr('disabled','disabled');
}

I love this code and it worked for a couple of months. Now all of a sudden the options are not updating to only show what is available after the initial load of the page. When selecting a variant after the first option it says UNAVAILABLE rather than the normal ADD TO CART.

Any suggestions?

Thanks so much in advance, Aaron

Shopify.uniq is no longer available so this is no longer working.

Is there a an update to use in place of Shopify.uniq?

I've found this video- it uses this snippets and it works: https://youtu.be/dNjMDv5kWig

Thanks MichalHoss - the youtube does have slightly different method, and works.

Seems to be working for me. Thanks!

Should I be worried it will stop working?

Hi,
Can someone here help me with making this appear rtl? I can't find the part that creats the option's label before the select, so each of my "select" are right aligned, but the labels are floating (i guess) left..
I tried to use css but the page loads rtl and then it jumps back left..

There is a conflict when there is ONLY ONE variant option used on product page.
All is well when there are two or three variant options but in case client is using only one, then switch price/image or hiding the
undesired will not work properly

Changes to this piece of code, undesired has been commented out:

// Gathering values for the 2nd drop-down.
     // if (product.options.length > 1) {
        var key = variant.option1;
        Shopify.optionsMap[key] = Shopify.optionsMap[key] || [];
        Shopify.optionsMap[key].push(variant.option2);
        Shopify.optionsMap[key] = Shopify.uniq(Shopify.optionsMap[key]);
     // }

Any ideas on how to implement this in the new sectioned themes? I'm at a loss.

I'm having the same issue than xhorntail with the sectioned theme Jumpstart. When I try this tutorial: https://help.shopify.com/themes/customization/navigation/link-product-options-in-menus , it works perfectly on my product page but not on the section featured product of my home page.

Did someone has the same issue and found a solution ?

I'm the creator of the premium District theme, and this question comes up extremely often in support. Now that all the themes have updated to sections, this great guide stopped working. I spent some time this afternoon modifying the snippet to work with some of the changes sectioned themes saw.

• Added required methods from the deprecated options_selection.js
• Triggers an initial variant change
• Hides sold out variants with only one option (@knauso)

I have verified that it works with our District theme, and while it should work in theory with other sectioned themes it has not been tested.

https://gist.github.com/jonathanmoore/c0e0e503aa732bf1c05b7a7be4230c61

I read in one of the comments that in order to have the options greyed out & disabled, to remove a piece of code:
else {
$(this).addClass('soldout').hide().find(':radio').removeAttr('checked').attr('disabled','disabled');
}

The problem is that if I remove this piece of code, then the linked-options do not work anymore. Therefore the question is:
How to HIDE linked options BUT have DISABLED/GRAYED-OUT the products that are out of stock?

For example:
T-Shirt has 2 sizes and 3 colors as follows:
Sizes: S and M
Color: Black - available only for size S
Color: Blue - available for both size S and M
Color: White - available for both size S and M
Color White for size M is SOLD OUT

So in this context, I would like for color Black not be visible for size M, and color white to visible but grayed out for size M

What are the changes to be made to the above posted code to make this work?

Many thanks.

@simina89 - uncomment that line and instead remove .hide() from it. So should look like this:

$(this).addClass('soldout').hide().find(':radio').removeAttr('checked').attr('disabled','disabled');

you can also go ahead and remove .show() from the line above so it looks like:

$(this).removeClass('soldout').find(':radio').removeAttr('disabled','disabled').removeAttr('checked');

both .hide() and .show() are jQuery buddies that do exactly what they say they do, so you're just taking away that behavior.
so long as the class .soldout has style applied to it you should be good to go.

How To add please select option with this code. I have added this code and now by default variants are selected. I want please select option in the drop down and main image will show rather than showing first variant with image as default.

Thanks

I have the OOTSB Turbo theme. The code works in the editor but when viewing on the Live page the product page needs to be refreshed each time for the code to work. Any ideas how I can fix this?

I have the same problem as you KevinHitchins - page needs to be refreshed to get this to work. Have you had any luck since?

KevinHitchins and babyoriginals, I'm also wanting to use the OOTSB Turbo theme and have not been able to replace my existing theme for the same reason. Reached out to both Shopify support and OOTSB support, but neither were able to resolve the issue or commit to a future fix/update. Unfortunately my store absolutely requires this functionality so am completely out of luck until it is resolved. Shopify "Experts" have also been reluctant to try to fix this. Did either one of you manage to get this working yet? If so, please post an update to these comments, and I will do the same. Thank you.

Is it possible to get an update for Slate?

use "jQuery.unique" in the place of "Shopify.uniq"

This code works great on the product detail page, however it does not get applied within the Quick Shop modal window. I've got {% include 'linked-options' %} at the end of my theme.liquid file, but I'm not sure if the scripts need to be added somewhere else to work within the quick shop modal (it's fancybox with the Mobilia OOTSB theme). Any help would be greatly appreciated!

Uncaught TypeError: Shopify.uniq is not a function
I am seeing this error
How can i solve that?

I'm having the same problem as several others, the page needs to be manually refreshed each time to get this to work. Still wanting to use the OOTSB Turbo Theme. Very frustrating. Please let me know if you figured this out. Cheers!

I get a page jump to the top after completion of selections I am trying to stop. I think it relates to this piece of code. Anyone have any thoughts on what in the code snippet can be causing that? How to stop it? Thanks!!

i'm using Debut Theme and after implement this, nothing is happen. Anyone can help me?

This code works great for us using the Fasionopolism theme but - how do we only hide unavailable variants (such as a color/size that doesn't exist) and leave sold out variants to still show up but say 'sold out'?

Hey Please help me. Everything tried but not working for me.

jQuery(function($) {

I have tried this on symmetry theme but its not working can anyone help please?

@eddyparkinson I implemented both these fixes as well as removing defer="defer" from the vendor.js load and still nothing doing. Preview link below, any help would be much appreciated.

I'm getting Cannot read property 'length' of undefined on the loop that goes on
availableOptions = Shopify.optionsMap[key];
any idea how to solve this?

Hello, I get this error "availableOptions is undefined". Do you have any suggestions for that?

Hello, I get this error "availableOptions is undefined". Do you have any suggestions for that?

In my case, the issue was in the selector calls (lines 14, 18, 22, 23, 82 and 88). It originally was:

jQuery(".single-option-selector:eq

But when I looked at my code, the actual selector was missing the "single-" part, so the updated code ended up being:

jQuery(".option-selector:eq

&TLDR;

In the linked-options.liquid file, find and replace all instances of ".single-option-selector" with ".option-selector"

I have also applied the same script but its not working. I am using 'FLEX' theme by Out of Sandbox.

Actually, I have three option as below:

1. Color
2. Contrast Color
3. Size

linked-option script only hide the color option variants its not hiding the size and contrast color variants.

@muneeb434 Hello dude, your code is working for Brooklyn theme, thanks. But what if i want use "button" type, not "drop-down"? May be you know what to change in this code?

Excellent one.. trying hard for whole day.. and i found it at last

Was anyone able to implement this feature to the quickview cart option?

The code if you want to disable variants instead of hiding them. It also appends 'Sold Out'. Should look like this https://tppr.me/jjhlY

Is it possible to have this work for select elements instead of radio buttons?

It works for select elements.

@willimagrivera has a good idea but I had to make some corrections to get that code to work.

Here's what works for me:

First, make sure when you call the product form you add product JSON, here's how I placed that in the data-product-json attribute:

{%- assign product_data_json = product | json -%}
{% form 'product', product, novalidate: 'novalidate', data-product-json: product_data_json %}

Then in my utilities.js I just do this:

var Shopify = Shopify || {};

Shopify.optionsMap = {};

Shopify.arrayIncludes = function (t, e) {
  for (var o = 0; o < t.length; o++) {
    if (t[o] == e) return !0;
  }
  return !1;
};

Shopify.uniq = function (t) {
  for (var e = [], o = 0; o < t.length; o++) {
    Shopify.arrayIncludes(e, t[o]) || e.push(t[o]);
  }
  return e;
};

Shopify.updateOptionsInSelector = function(selectorIndex) {
    
  switch (selectorIndex) {

I've tried trouble shooting using the comments on here to either grey out or even just show out of stock options while also having the linked options work, but I haven't had any luck. I can get one to work or the other, but never at the same time.

I am working with the Out of the Sandbox theme Mobilia. Has anyone been able to make it work with that theme?

I changed also the way to select form from :

$('form[action="/cart/add"]')

to

$('form[action*="/cart/add"]')

Because when you are on a locale (/en), it does not match, and it should !

Which site sir
