I want my customers to customize the product as they they like. So In the product page I have to add options to choose color o f the t-shirt , add text and upload images (their design) etc. But I could not do it @Savior

@Sreehari

You need something like this ? Please confirm.

This needs some code changes at admin side. If you don’t have knowledge about liquid coding please DM me.

@Savior Yeah absolutely. Although I need one more option , to add files

@Sreehari

Okay please DM me.

I am new to here hence, I don’t have the option to DM yet @Savior
