What is the best way to call/embed the form: through JS or Html?

Question

JavaScript

Greetings
I'm thinking about how best to display the feedback form on the site. The form is displayed in a modal window. There are two options:

1. Push the entire form code into a JS file, it will be stored there and appear in the page markup only when the button is clicked
   
2. Embed the form directly and immediately in the Html code.
   

It is clear that you should not bother too much in this matter, but perhaps there are, for example, practices unfamiliar to me, according to which it is better to do this and not otherwise. What do you think?

Answer 1

Immediately embed in the page with display:none. Show when needed
