My options:

1) load all with the page, use js to show/hide fields as needed

2) have js clone/add fields when a button is pressed

Either is fine, but option 1 is the least work at the moment(but I guess more bandwidth consumption in the long run for billions of queries, but I'm not worrying about this now): what is the simplest way with jquery/bootstrap to hide show subsequent parts of the field as necessary? I'm not really a js person, but looking into it it should be simple enough, but I'm posting to see what solutions people have to offer while I work on this.

Answer 1

You can use .hide()

$('#id').hide();

$('table').hide(); // Hides all the tables

$('#identifier-0').show() // Shows the table wit id="identifier-0"
