Can I add more than one form on the same page?
Yes, you can. There is no limit to the number of forms that you can show on the same page.
Can I add only one product variation to my form?
Sure, the plugin also supports variable products. You will be able to add one or more variations of the same product into the form and exclude the others.
Which products are searched if I use the form placed before the list of products?
The form allows searching the selected list of products, and not the whole product catalog on your website.
