Point on an anchor on bootstrap modal opening - html

Question

I would like to open a help modal, but depending on which link is clicked I need to focus on specific anchor like we do on a FAQ page.
On a page we will add #myAmazingTitle on href link (e.g FAQ for focusing the display on specific dom element.
<h1>My first title</h1>
<h1 id="myAmazingTitle">My Amazing Title</h1> <== Display will be focused on this title
....
I would like to have the same behavior with a bootstrap modal.
Is it possible and how?
This is Fiddle for this issue.

Use relatedTarget and HTML data-* attributes to specify target element selector (or anchor) and send this value to a handler of shown.bs.modal event. See example of usage below.
$('#exampleModal').on('shown.bs.modal', function(e) {
var recipient = $(e.relatedTarget).data('focus');
$(this).find( recipient ).focus();
});
