Select2 doesn't work when embedded in a bootstrap modal
JqueryTwitter BootstrapJquery Select2Jquery Problem Overview
When I use a select2 (input) in bootstrap modal, I can't type anything into it. It's like disabled? Outside the modal select2 works fine.
Working example: http://jsfiddle.net/byJy8/1/ code:
<!-- Modal -->
<div id="myModal" class="modal hide fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h3 id="myModalLabel">Panel</h3>
</div>
<div class="modal-body" style="max-height: 800px">
<form class="form-horizontal">
<!-- Text input-->
<div class="control-group">
<label class="control-label" for="vdn_number">Numer</label>
<div class="controls">
<!-- seleect2 -->
<input name="vdn_number" type="hidden" id="vdn_number" class="input-large" required="" />
</div>
</div>
</form>
</div>
<div class="modal-footer">
<button class="btn" data-dismiss="modal" aria-hidden="true">Close</button>
<button class="btn btn-primary">Save changes</button>
</div>
</div>
JS
$("#vdn_number").select2({
placeholder: "00000",
minimumInputLength: 2,
ajax: {
url: "getAjaxData/",
dataType: 'json',
type: "POST",
data: function (term, page) {
return {
q: term, // search term
col: 'vdn'
};
},
results: function (data) { // parse the results into the format expected by Select2.
// since we are using custom formatting functions we do not need to alter remote JSON data
return {results: data};
}
}
});

Solution 1 - Jquery
Ok, I've got it to work.
change
<div id="myModal" class="modal hide fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h3 id="myModalLabel">Panel</h3>
</div>
<div class="modal-body" style="max-height: 800px">
to
<div id="myModal" class="modal hide fade" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h3 id="myModalLabel">Panel</h3>
</div>
<div class="modal-body" style="max-height: 800px">
(remove tabindex="-1" from modal)
Solution 2 - Jquery
For Select2 v4:
Use dropdownParent
to attach the dropdown to the modal dialog, rather than the HTML body.
<!-- Modal -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button>
<h4 class="modal-title" id="myModalLabel">Modal title</h4>
</div>
<div class="modal-body">
<select id="select2insidemodal" multiple="multiple">
<option value="AL">Alabama</option>
...
<option value="WY">Wyoming</option>
</select>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>
<script>
$(document).ready(function() {
$("#select2insidemodal").select2({
dropdownParent: $("#myModal")
});
});
</script>
This will attach the Select2 dropdown so it falls within the DOM of the modal rather than to the HTML body (the default). See https://select2.org/dropdown#dropdown-placement
Solution 3 - Jquery
I found a solution to this on github for select2
https://github.com/ivaynberg/select2/issues/1436
For bootstrap 3, the solution is:
$.fn.modal.Constructor.prototype.enforceFocus = function() {};
Bootstrap 4 renamed the enforceFocus
method to _enforceFocus
, so you'll need to patch that instead:
$.fn.modal.Constructor.prototype._enforceFocus = function() {};
Explanation copied from link above:
> Bootstrap registers a listener to the focusin event which checks whether the focused element is either the overlay itself or a descendent of it - if not it just refocuses on the overlay. With the select2 dropdown being attached to the body this effectively prevents you from entering anything into the textfield. > > You can quickfix this by overwriting the enforceFocus function which registers the event on the modal
Solution 4 - Jquery
Just remove tabindex="-1"
and add style overflow:hidden
Here is an example:
<div id="myModal" class="modal fade" role="dialog" style="overflow:hidden;">
<!---content modal here -->
</div>
Solution 5 - Jquery
Set the dropdownParent. I had to set it on .modal-content within the modal or the text would end up centered.
$("#product_id").select2({
dropdownParent: $('#myModal .modal-content')
});
Solution 6 - Jquery
.select2-close-mask{
z-index: 2099;
}
.select2-dropdown{
z-index: 3051;
}
This is my solution with select2 4.0.0. Just override the css right below the select2.css import. Please make sure the z-index is greater than your dialog or modal. I just add 2000 on the default ones. Cause my dialogs' z-index are about 1000.
Solution 7 - Jquery
Answer that worked for me found here: https://github.com/select2/select2-bootstrap-theme/issues/41
$('select').select2({
dropdownParent: $('#my_amazing_modal')
});
Also doesn't require removing the tabindex
.
Solution 8 - Jquery
According to the official select2 documentation this issue occurs because Bootstrap modals tend to steal focus from other elements outside of the modal.
By default Select2 attaches the dropdown menu to the element and it is considered "outside of the modal".
Instead attach the dropdown to the modal itself with the dropdownParent setting:
$('#myModal').select2({
dropdownParent: $('#myModal')
});
See reference: https://select2.org/troubleshooting/common-problems
Solution 9 - Jquery
I had the same issue, updating z-index
for .select2-container
should do the trick. Make sure your modal's z-index
is lower than select2's.
.select2-container {
z-index: 99999;
}
Updated: In case above code doesn't work properly, also remove tabindexes from your modal as @breq suggested
Solution 10 - Jquery
This Problem Sloved Working For Me Single Jquery Function
$('#myModal .select2').each(function() {
var $p = $(this).parent();
$(this).select2({
dropdownParent: $p
});
});
Solution 11 - Jquery
For bootstrap3 versions, just use this code on document ready:
$(document).ready(function(){
$.fn.modal.Constructor.prototype.enforceFocus = function () {};
});
Solution 12 - Jquery
In my case I had the same problem with two modals and all was resolved using:
$('.select2').each(function() {
$(this).select2({ dropdownParent: $(this).parent()});
})
As in the project issue #41 an user said.
Solution 13 - Jquery
I had a similar problem and I fixed with
$('#CompId').select2({
dropdownParent: $('#AssetsModal')
});
and modal with select
<div class="modal fade" id="AssetsModal" role="dialog"
aria-labelledby="exampleModalCenterTitle"
aria-hidden="true" style="overflow:hidden;" >
<div class="modal-dialog modal-dialog-centered" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLongTitle" >Добави активи</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
<form role="form" action="?action=dma_act_documents_assets_insert&Id=<?=$ID?>"
method="post" name="dma_act_documents_assets_insert"
id="dma_act_documents_assets_insert">
<div class="form-group col-sm-12">
<label for="recipient-name" class="col-form-label">Актив:</label>
<span style="color: red">*</span>
<select class="form-control js-example-basic-single col-sm-12"
name="CompId" id="CompId">
<option></option>
</select>
</div>
</form>
</div>
</div>
</div>
but I don't know why the select menu is smaller than other fields
and it starting like that when start using select2. When I remove it, all is ok.
Is there some one to share some experince about that.
Thanks.
Solution 14 - Jquery
change select2.css file
z-index: 9998;
...
z-index: 9999;
...
z-index: 10000;
to
z-index: 10000;
...
z-index: 10001;
...
z-index: 10002;

Just to understand better how tabindex elements works to complete accepted answer :
> The tabindex global attribute is an integer indicating if the element can take input focus (is focusable), if it should participate to sequential keyboard navigation, and if so, at what position. It can take several values:
-a negative value means that the element should be focusable, but should not be reachable via sequential keyboard navigation;
-0 means that the element should be focusable and reachable via sequential keyboard navigation, but its relative order is defined by the platform convention;
-a positive value means should be focusable and reachable via sequential keyboard navigation; its relative order is defined by the value of the attribute: the sequential follow the increasing number of the tabindex. If several elements share the same tabindex, their relative order follows their relative position in the document.

$('.modal').on('shown.bs.modal', function (e) {
$(this).find('.select2me').select2({
dropdownParent: $(this).find('.modal-content')
});
})
Solution 17 - Jquery
to use bootstrap 4.0 with server-side(ajax or json data inline), you need to add all of this:
$.fn.modal.Constructor.prototype._enforceFocus = function() {};
and then when modal is open, create the select2:
// when modal is open
$('.modal').on('shown.bs.modal', function () {
$('select').select2({
// ....
});
});
Solution 18 - Jquery
If you have a problem with the iPad keyboard which hide the bootstrap modal while clicking on the select2 input, you can resolve this by adding the following rule after the initialization of the select2
input :
if (navigator.userAgent.match(/iPhone|iPad|iPod/i)) {
var styleEl = document.createElement('style'), styleSheet;
document.head.appendChild(styleEl);
styleSheet = styleEl.sheet;
styleSheet.insertRule(".modal { position:absolute; bottom:auto; }", 0);
document.body.scrollTop = 0; // Only for Safari
}
Taken from https://github.com/angular-ui/bootstrap/issues/1812#issuecomment-135119475
EDIT: If your options are not shown properly, you need to use the dropdownParent
attribute when initializing select2
:
$(".select2").select2({
dropdownParent: $("#YOURMODALID")
});
Good luck (:

Based on @pymarco answer I wrote this solution, it's not perfect but solves the select2 focus problem and maintain tab sequence working inside modal
$.fn.modal.Constructor.prototype.enforceFocus = function () {
$(document)
.off('focusin.bs.modal') // guard against infinite focus loop
.on('focusin.bs.modal', $.proxy(function (e) {
if (this.$element[0] !== e.target && !this.$element.has(e.target).length && !$(e.target).closest('.select2-dropdown').length) {
this.$element.trigger('focus')
}
}, this))
}
Solution 20 - Jquery
Use this code on your page
$(function () {
$(".select2").select2({
dropdownParent: $('#myModal')
});
$("#myModal").on('change', '#vdn_number', function () {
var term = $(this).val();
ajax: ({
url: "getAjaxData/",
dataType: 'json',
type: "POST",
data: function (term, page) {
return {
q: term, // search term
col: 'vdn'
};
},
results: function (data) { // parse the results into the format expected by Select2.
// since we are using custom formatting functions we do not need to alter remote JSON data
return { results: data };
}
});
});
});
I think this will help you

$("#IlceId").select2({

dropdownParent: $("#IlceId").parent(),
escapeMarkup: function (m) {
return m;
},
});
this code is working. Thank you.

Okay, I know I'm late to the party. But let me share with you what worked for me. The tabindex and z-index solutions did not work for me.
Setting the parent of the select element worked as per the common problems listed on select2 site.
Solution 23 - Jquery
I solved this generally in my project by overloading the select2
-function. Now it will check if there is no dropdownParent and if the function is called on an element that has a parent of the type div.modal
. If so, it will add that modal as the parent for the dropdown.
This way, you don't have to specify it every time you create a select2-input-box.
(function(){
var oldSelect2 = jQuery.fn.select2;
jQuery.fn.select2 = function() {
const modalParent = jQuery(this).parents('div.modal').first();
if (arguments.length === 0 && modalParent.length > 0) {
arguments = [{dropdownParent: modalParent}];
} else if (arguments.length === 1
&& typeof arguments[0] === 'object'
&& typeof arguments[0].dropdownParent === 'undefined'
&& modalParent.length > 0) {
arguments[0].dropdownParent = modalParent;
}
return oldSelect2.apply(this,arguments);
};
// Copy all properties of the old function to the new
for (var key in oldSelect2) {
jQuery.fn.select2[key] = oldSelect2[key];
}
})();
Solution 24 - Jquery
This will work for all
body .select2-container {
z-index: 9999 !important;
}
Solution 25 - Jquery
If you use jquery mobile popup you must rewrite _handleDocumentFocusIn function:
$.mobile.popup.prototype._handleDocumentFocusIn = function(e) {
if ($(e.target).closest('.select2-dropdown').length) return true;
}

I have the same problem with the select2
in bootstrap modal
, and the solution was to remove the overflow-y: auto;
and overflow: hidden
; from .modal-open
and .modal classes
Here is the example of using jQuery
to remove the overflow-y
:
$('.modal').css('overflow-y','visible');
$('.modal').css('overflow','visible');
Solution 27 - Jquery
i had this problem before , i am using yii2 and i solved it this way
$.fn.modal.Constructor.prototype.enforceFocus = $.noop;
Solution 28 - Jquery
I had a semi-related issue in an application so I'll put in my 2c.
I have multiple modals with forms containing select2 widgets. Opening modal A, then another modal inside modal A, would cause select2 widgets inside modal B to disappear and fail to initialize.
Each of these modals were loading the forms via ajax.
The solution was to remove the forms from the dom when closing a modal.
$(document).on('hidden.bs.modal', '.modal', function(e) {
// make sure we don't leave any select2 widgets around
$(this).find('.my-form').remove();
});
Solution 29 - Jquery
you can call select2 trigger again inside your $(document)
$(".select2").select2({
width: '120'
});

If you using stisla
and use firemodal :
$('#modal-create-promo').click(()=>{
setTimeout(()=>{
$('#fire-modal-1').removeAttr('tabindex');
});
});
$("#modal-create-promo").fireModal({
...
});
It's work for me
Solution 33 - Jquery
You shouldn't stuck your dropdown to the modal as suggested in most of the answer. If your select2 is at the bottom of the modal and you need to scroll down to find it then you will have a dropdown's position problem because you stuck it on the modal.
Instead of this you should set the dropdown parent to the input parent. In your case it should look like this
$(document).ready(function() {
$("#vdn_number").select2({
dropdownParent: $("#vdn_number").parent()
});
});

var evt = "scroll.select2"
$(e.target).parents().off(evt)
$(window).off(evt)
})
})
