How can I add a size filter to my product page?

Hi I would like to add the size menu to the product page

most of the items I sell are only available in some sizes

so I would like that when a customer brows he can see what’s in his size and he doesn’t have to click each product to find his size

Hi @yitcee

Which theme are you using? Adding this feature to a theme that doesn’t support it out of the box could be challenging for a non-developer.

Please send your site and if your site is password protected, please send me the password. And send me the theme name you are using.
I will check it for you.

Sorry, simple theme doesn’t support this. If you want, you need to add Liquid code to it and then display it with CSS.
