Hi,

I am trying to prepopulate my form through URL Paramaters. It works perfectly with text input fields but I could not figure out how it works with checkbox fields.

Is this possible with mautic forms?

I could not find documentation about it. Is there already a post that explains prepoluations of mautic forms?

Thanks!
