Can't type in Option text box or text area box

So, I added an option for customers to be able to modify an order by typing notes under each item before checkout but when I open the product details, I am not able to type anything in

Hello Rob,

The option with text type should be available for shopping to type the content in a text box on the product details page.

If it does not work like that, please submit a new ticket to EShop category to send me the your site information so I can help you.

Sincerely, Giang
