Is it easy to program a link button so that some of the fields in the contact form 7 can be filled out in advance?
Description of what I want: I have a page with links to my different products. These can be accessed by pressing a button. For example, I press the button for product b, how do I get product b checked (ticked/pre-filled) for in advance when I go into the contact form for the product? I know there is something you can do with the link that leads to the form. I have done something similar a long time ago but I can not remember the details.
Thank you in advance!
