Thank you, I don't see the text style in the woo attribute system (https://prnt.sc/C8cRrer2o6Dc). Can you explain more clearly for me?

Thanks

Dear support team,

I am developing an e-commerce website. My product contains many technical specifications. In your theme I only found WP's default attributes, which are used as variations for products or filters, I did not find any attributes of type text or text area to contain product information.

I ask you to guide me or advise me on which plugin to use that is compatible with your theme.

Thanks
Ton Nguyen
