</div>
</div>
</div>
<a class="btn btn-block waves-button waves-effect" data-toggle="modal" href="#modal">Toggle Modal</a>
<div class="form-group">
<div class="row">
<div class="col-md-10 col-md-push-1">
<button class="btn btn-block btn-blue waves-button waves-effect waves-light">Sign In</button>
</div>
</div>
</div>
</form:form>
when I click on the link in form which is
<a class="btn btn-block waves-button waves-effect" data-toggle="cat" href="#modal">Show cat</a>
I want to show the following
<div aria-hidden="true" class="modal fade" id="cat" role="dialog" tabindex="-1">
<div class="modal-dialog modal-xs">
<div class="modal-content">
<div class="modal-heading">
<a class="modal-close" data-dismiss="modal">×</a>
<h2 class="modal-title">Seclect Categories</h2>
</div>
<div class="modal-inner">
<select>
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="mercedes">Mercedes</option>
<option value="audi">Audi</option>
</select>
</div>

</div>
</div>
</div>
</div>
I want to get values selected from select and submit them when I submit the form using Javascript, I'm unable to place the select field in form for some reason.


You will need to use a javascript function. You can either have the cat div loaded from the beginning and hidden using javascript to show/hide it or you can call it via Ajax.
I included the div in your form and set the style to hidden with javascript either revealing it or hiding it on click. You can remove the if and just set to to display block when clicked if you don't want to hide it again. It's worth noting that this will not clear the values. If you want to clear values when closing it then you should call it with AJax and clear the div when closing.

following is the HTML code for modal
<div id="cntdetail" class="modal show fade" data-backdrop="static" role="dialog">
<div class="modal-dialog modal-dialog-centered">
<div class="modal-content">
<div class="modal-header">

<button type="button" class="btn btn-danger" data-dismiss="modal">
<i class="fa fa-close"></i>
Close
</button>
</div>
</div>
</div>
</div>
following is the JavaScript for event firing for modal show
<script>
$(function () {
$('#cntdetail').on('show.bs.modal', function (e) {
alert("a");
});
});
</script>

Try activating the modal via javascript using class instead of data-target.
$(".yourModalClassHere").click(() => {
$('#cntdetail').modal('show');
})
$('#cntdetail').on('show.bs.modal', function (e) {
alert("a");
});

use
modal.find("#main_menuid").val(div.data('mainid'));
here's a sample.
$('#modal-edit').on('show.bs.modal', function (event) {
var div = $(event.relatedTarget) // Tombol dimana modal di tampilkan
var modal = $(this)
// Isi nilai pada field
modal.find('#sub_menuid').attr("value",div.data('id'));
modal.find("#main_menuid").val(div.data('mainid'));
modal.find('#nama_submenu').attr("value",div.data('nama'));
modal.find('#link').attr("value",div.data('link'));
/*modal.find('#icon').attr("value",div.data('icon'));*/

<div class="modal-footer">
<button data-dismiss="modal" class="btn btn-default" type="button">Close</button>
</div>
</div>
Now what's happening in my code is when user clicks on above
<div class="panel-body" data-toggle="modal" href="ajax_event_detail.php?event_id=512" data-target="#myModal-event" style="cursor: pointer;"></div>
The first part of code opens up, then the data fetch is going on then suddenly the second part of code i.e. the data fetched gets added to the modal. I'm not understanding how this is happening.
The jQuery which is doing this is as follows but I didn't understand what it is doing when that hide event is being called etc. etc. Please clear my doubts by making me understand below code.
$('body').on('hidden.bs.modal', '.modal', function () {
console.log('Hi *');
$("#myModal-event .modal-body").html(' Loading... ');
$(this).removeData('bs.modal');
});
Thanks.

This executes when the .modal (modal window) gets closed. So, whenever you open a modal window with the class modal (obviously), at some point it gets closed. When that modal window gets hidden (or closed) the event hidden.bs.modal gets triggered and the function gets executed.
This is not managed by the user (you didn't write explicit code) but the Bootstrap library has it built in.
From the Bootstrap Documentation:
hidden.bs.modal: This event is fired when the modal has finished being hidden from the user (will wait for CSS transitions to complete).
Sample Code:
$('#myModal').on('hidden.bs.modal', function (e) {
// do something when this modal window is closed...
});
To answer the queries in the comments, you have:
$("#myModal-event .modal-body").html(' Loading... '); sets the content of the modal window to be Loading....
$(this).removeData('bs.modal'); - This tells Bootstrap to clear everything on the close of the modal window, so you won't get cached content. See more at Clear Bootstrap Modal content after close.

</div>
<!-- /.modal-content -->
</div>
<!-- /.modal-dialog -->

As far i can understand your question, you are having problem in passing the id to Modal, if yes, then you can do the following:
In your a-href code use data-id:
<a class="btn btn-info open_modal" data-toggle="modal" data-id="<?php echo productid;?>" data-target="#myModalDetail" href="#myModalDetail"> <i class="fa fa-edit"></i> </a>
Javascript:
$(document).on("click", ".open_modal", function () {
var product_id = $(this).data('id');
});
