I have a problem and don't know how to do it. Probably with JS. I am using Contact form 7 plugin in my wordpress page. I need to do a dropdown(right), placeholder text (right). So UX needs to be first to select an option from the dropdown list (picture: "Dnevna soba ( )"). That option posts in the form and you need to input additional text (picture: between the "( )") in the dropdown selection.
How can I do this ?
