Answer 1

I dont know which tool are you using to design your UI, anyway this is concerning functionality, not design. In that point, i need to know wich language do you want (or can) use. For example, in PHP, it's very simple, you can make something like: (create php file) downloadpdf.php 1st: (if you want to generate pdf "on the fly":

<?php
function download($foo){
    content headers (type, force-download, etc)
    database select to get data or harcode it.
    echo data
}
?>

and call this function with some id to select from database or something (ignore if you want to hardcode it)

Other option to download a file, if it's stored on server is making a link to this file (statically or dyamically). If you wanna take control to file downloads, check this post:

I don't mean that it can be done with UI designer tools, and it's not concerned if it's from a form or not.

You should create link and variable which type is javascript expression. On Variable value write

return "/bonita/portal/" + $data.context.mainDoc_ref.url;

On link URL write your variable and to text

Download: {{context.mainDoc_ref.fileName}}

Here you can find excellent example for this case
