Adding custom option to let customer to input

[Moshi]

I have multiple options columns: Large Size, Medium Size, Samll Size...Now I need to add another column "custom" which is open for customers to design how big the cup it is, we will make the cups according to customers' input number. Do I need to add JS function to implement it?

Sorry, it's open for internal use only for now. I need to add behavior: given a mulitple choice column, when I select "custom" , it will generate a column to let use to type the desired value. I know it's piece of cake thru HTML and JS, wonder how to insert it into Shopify liquid languge?

Hi @Moshi,

You can consider using the Easify Product Options app to quickly create number text fields. This app not only allows customers to input their specific dimensions but also provides a streamlined solution for price calculation based on those custom sizes.

Please share more details about your product and pricing and I'll guide you on how to set it up with the app.

Thank you for the answer! But I still want to know, is there any way to hard code it, like changing the code using HTML and JavaScript?
