How to add product data to WPForms Lite form?

Question

WordPress

I planned to create hidden fields for product attributes and fill them in using js on the page. But hidden fields are not available in Lite version. Add simple ones with display: none? Or is it better to use some hook to add fields? Is there an example of how to do this? Or you can find a plugin like Buy one click WooCommerce, you just have to edit the styles
