Nevermind, I’ve got it figured out. Will need a bit of brushing up on my JS syntax to get this to work, but that’s entirely doable. Thanks again @mishav.
Update: Here’s the code I’m using which works perfectly. I’ve set it up to run this code anytime a new input is toggled to display on the page.
jQuery(document).ready(function($) {
$(‘a, input, select, button, textarea’).attr(‘tabindex’,0);
});
