Add a size chart to product pages

If you sell clothing items that require customers to know their size before they make a purchase, you can add a custom size chart to your product page.

All products that require reference to the size chart must have a Size option

• Congrats, You’ve completed the coding parts.

Theme admin

• Create navigation where size chart should be displayed to [set collection pages]

• Now go to random product details from the collection which you’ve set to the nav. Set the template product.sizechart

• See the product from your store and customize this from theme section settings. You’ll see an option to add content > add your sizechart > give it a name > select the nav which you’ve created > add the size in the content

Congrats, You’ve completed this feature.
