One of my clients product for her site is customisable … for this product I need the customers to choose the product, but then they need to be able to write a message about the customisation .. so it would just require a text input field to be added to one of the products.
Regretfully this isn’t a feature offered by X. It could be possible with custom development, but this would be outside the scope of support we can offer. You may wish to consult a developer to assist you with this. X is quite extensible with child themes, so there are plenty of possibilities. Thanks for understanding. Take care!
