Is it possible to add another product as a product option?

Is it possible to limit the min/max characters in a text input or in text area options?

Is it possible to copy the same configuration from one website to another?
No, it is possible to copy the configuration to a different site. Yet, you can do it manually by copying the following tables from the database:
“yith_wapo_groups” and “yith_wapo_types” (for version 1.x)
“yith_wapo_blocks” and “yith_wapo_addons” (for version 2.x).
Can I show the content of the field “text” in a new order email?
Does the plugin work with REST API?
No, our Product Add-Ons plugin does not work with REST API.
I want to charge the customer based on the text length, like $1 for every letter. How can I do that?
