Select2 with tags set to true: Is it possible to always keep the placeholder after selecting the options? - jquery-select2

I want the placeholder to be shown always whether the option is added, selected, or removed. Currently, the placeholder shows after removing the options or after adding the new options. But when the option is selected from the dropdown the placeholder will disappear. This may be the original functionality of the seelct2 plugin. Is there any way to keep the placeholder always visible?
$("select.add-tags").select2({
tags: true,
dropdownParent: $(".select-tags"),
placeholder: "Start typing the tag name..."
});
if ($("select.add-tags").select2("data").length) {
$("select.add-tags")
.next()
.find(".select2-search.select2-search--inline .select2-search__field")
.attr("placeholder", "Placeholder on default");
$("select.add-tags")
.next()
.find(".select2-search.select2-search--inline .select2-search__field")
.css("width", "200px");
}
$("select.add-tags").on("select2:select", function (evt) {
// console.log($(this).val());
console.log("select2 : select");
var element = evt.params.data.element;
var $element = $(element);
$element.detach();
$(this).append($element);
$(this).trigger("change");
if (
$(".select2-search.select2-search--inline .select2-search__field").is(
":focus"
)
) {
console.log("tag input fpcused");

);
$(".select2-search.select2-search--inline .select2-search__field").css(

"200px"
);
}
});
$("select.add-tags").on("select2:unselect", function () {
console.log($(this).val());
console.log("select2 : unselect");
if ($("select.add-tags").val().length == 0) {
$(".select2-search.select2-search--inline .select2-search__field").attr(

Autocomplete combobox widget force change

I'm getting absolutely no where in getting the underlying select to fire a changed event after a autocomplete value is selected.
How can I force a change within the widget. From what I can find I need to
trigger a select event and trigger a change with something like this, but I can't get it to work
select: function(event,ui) {
this.value=ui.item.value;
$(this).trigger('change');
return false; }
(function( $ ) {
$.widget("st.comboboxAutocomplete", {
options: {
minLength: 0,
showDropdown: false,
width: '',
Id: '',
},
_create: function () {
this.wrapper = $("<span>")
.addClass("st-comboboxAutocomplete")
.css({ 'padding': '0px 0px', 'width': this.options.width})
.insertAfter(this.element);
this.element.hide();
this._createAutocomplete();
if (this.options.showDropdown)
{
this._createShowAllButton();
}
},
_createAutocomplete: function () {
var selected = this.element.children(":selected"),
value = selected.val() ? selected.text() : "";
this.input = $("<input>")
.appendTo(this.wrapper)
.val(value)
.attr("title", "")
.attr("id", this.options.Id)
.addClass("st-comboboxAutocomplete-input")
.css('margin-right', '5px')
.autocomplete({
delay: 0,
minLength: this.options.minLength,
source: $.proxy(this, "_source"),
});
this._on(this.input, {
autocompleteselect: function (event, ui) {
ui.item.option.selected = true;
this._trigger("select", event, {
item: ui.item.option
});
},
autocompletechange: "_removeIfInvalid"
});
},
_createShowAllButton: function () {
var input = this.input,
wasOpen = false;
$("<a>")
.attr("tabIndex", -1)
.attr("title", "Show All Items")
.tooltip()
.css('background-color', '#fff')
.appendTo(this.wrapper)
.button({
icons: {
primary: "ui-icon-triangle-1-s"
},
text: false
})
.removeClass("ui-corner-all")
.addClass("st-comboboxAutocomplete-toggle ui-corner-right")
.on("mousedown", function () {
wasOpen = input.autocomplete("widget").is(":visible");
})
.on("click", function () {
input.trigger("focus");
// Close if already visible
if (wasOpen) {
return;
}
// Pass empty string as value to search for, displaying all results
input.autocomplete("search", "");
});
},
_source: function (request, response) {
var matcher = new RegExp($.ui.autocomplete.escapeRegex(request.term), "i");
response(this.element.children("option").map(function () {
var text = $(this).text();
if (this.value && (!request.term || matcher.test(text)))
return {
label: text,
value: text,
option: this
};
}));
},
_removeIfInvalid: function (event, ui) {
// Selected an item, nothing to do
if (ui.item) {
return;
}
// Search for a match (case-insensitive)
var value = this.input.val(),
valueLowerCase = value.toLowerCase(),
valid = false;
this.element.children("option").each(function () {
if ($(this).text().toLowerCase() === valueLowerCase) {
this.selected = valid = true;
return false;
}
});
// Found a match, nothing to do
if (valid) {
return;
}
// Remove invalid value
this.input
.val("")
.attr("title", value + " didn't match any item")
.tooltip("open");
this.element.val("");
this._delay(function () {
this.input.tooltip("close").attr("title", "");
}, 2500);
this.input.autocomplete("instance").term = "";
},
_destroy: function () {
this.wrapper.remove();
this.element.show();
}
});
})( jQuery );
$(function() {
$( "#combobox" ).comboboxAutocomplete();
$("#combobox").change(function() {
alert(this.value);
});
});

</div><!-- End demo-description -->
In case inquiring minds want to know, I solved this with the following
_createAutocomplete: function () {
var selected = this.element.children(":selected"),
value = selected.val() ? selected.text() : "";
this.input = $("<input>")
.appendTo(this.wrapper)
.val(value)
.attr("title", "")
.attr("id", this.options.Id)
.addClass("st-comboboxAutocomplete-input")
.css('margin-right', '5px')
.autocomplete({
delay: 0,
minLength: this.options.minLength,
source: $.proxy(this, "_source"),
change: $.proxy(this, "_change")
});
this._on(this.input, {
autocompleteselect: function (event, ui) {
ui.item.option.selected = true;
this._trigger("select", event, {
item: ui.item.option
});
},
autocompletechange: "_removeIfInvalid"
});
}
_change: function (event, ui) {
this.value = ui.item.value;
this.element.trigger('change');
return false;
}
This will fire a change when you tab or exit the autocomplete. If you want it to fire the change on select then use
select: $.proxy(this, "_select")
_select: function (event, ui) {
this.element.trigger('change');
},

Jquery Mobile Filterable Select Long List

Here's the solution if you still need it:
The demo itself has some errors. Here is a way to do it:
// demo-dialog is ID of selectmenu (demo) + (-dialog) which is added
// by jQM dynamically upon creating a custom selectmenu
$(document).on("pagecreate", "#demo-dialog", function (e) {
var form = $("<form><input data-type='search'/></form>"),
page = $(this);
$(".ui-content", this)
.prepend(form);
form.enhanceWithin()
.on("keyup", "input", function () {
var data = $(this).val().toLowerCase();
$("li", page).addClass("ui-screen-hidden")
.filter(function (i, v) {
return $(this).text().toLowerCase().indexOf(data) > -1;
}).removeClass("ui-screen-hidden");
});
$(document).on("pagecontainerhide", function () {
$("#demo-menu li").removeClass("ui-screen-hidden");
$("input", form).val("");
});
});
For reference:
https://forum.jquery.com/topic/cannot-read-property-jqmdata-of-undefined
This seemed to fix it for me -
In the 'pagecontainerhide' handler, change the argument in the
pageIsSelectmenuDialog function from 'data.toPage' to 'data.prevPage' as in:
if ( !pageIsSelectmenuDialog( data.prevPage ) ) {
       return;
}

JQM Change Select icon to Notext

In trying to keep website responsive I want to hide the text from a select menu when the screen is below a certain size.
I use something similar to remove button text.
function resizeBtn() {
var activePage = $.mobile.pageContainer.pagecontainer("getActivePage");
if ($(window).width() <= 490) {
$("#opt_user_btn.ui-btn-icon-left", activePage).toggleClass("ui-btn-icon-notext ui-btn-icon-left");
$( "#storeselect", activePage ).selectmenu( "option", "iconpos", "notext" );
} else {
$("#opt_user_btn.ui-btn-icon-notext", activePage).toggleClass("ui-btn-icon-left ui-btn-icon-notext");
$( "#storeselect", activePage ).selectmenu( "option", "iconpos", "notext" );
}
}
And the html is along the lines of:
<form><select name="storeselect" id="storeselect" data-native-menu="true" data-iconpos="left" onChange="this.form.submit();" >
<option value="1">1</option>
<option value="2">2</option>
</select>
</form>
I've looked at JQM info but not figured it out yet. Help would be appreciated. Thank you. :)
Inspecting the select bar the text for the selected option is in a span tag. One solution is to add a class with opacity:0 to the span
<div id="storeselect-button" class="ui-btn ui-icon-carat-d ui-btn-icon-left ui-corner-all ui-shadow"><span>Option 1</span><select name="storeselect" id="storeselect" data-native-menu="true" data-iconpos="left">
<option value="1">Option 1</option>
<option value="2">Option 2</option>
</select></div>
Demo
http://jsfiddle.net/mjk0f0t7/
Jquery
$(window).on('resize change', function () {
if ($(window).width() <= 490) {
$("#storeselect-button").find("span").addClass("noshow")
} else {
$("#storeselect-button").find("span").removeClass("noshow");
}
});
Css
.noshow {
opacity:0;
}
To hide or style the icon also
$("#storeselect").append('<style>.ui-btn-icon-left:after{opacity:0}</style>');
Demo
http://jsfiddle.net/wuLccyda/
To add ui-btn-icon-notext class simply use addClass and refresh the select menu
$(window).on('resize', function () {
if ($(window).width() <= 490) {
$("#storeselect").addClass("ui-btn-icon-notext")
$('#storeselect').selectmenu('refresh', true);
} else {
$("#storeselect").removeClass("ui-btn-icon-notext")
$('#storeselect').selectmenu('refresh', true);
}
});

Select2 with a checkbox list for a multiple select

I need to implement a select similar to this http://www.erichynds.com/examples/jquery-ui-multiselect-widget/demos/
I want to use select2 for this, but I haven't been able to find anything from the creator of the select2 that would support this style of dropdown with checkboxes in it. Does anyone know a way to do this?
I've faced a similar need but was not able to find it.
The solution I've came across was using the flag closeOnSelect set to false
$("#yadayada").select2({closeOnSelect:false});
http://jsfiddle.net/jEADR/521/
Seems this is old post, but as it is very common issue, I`m posting this here.
I found that the author already added a plugin to select2 for this feature to have checkbox-like selection and the dropdown does not hide on click:
https://github.com/wasikuss/select2-multi-checkboxes
Example:
$('.select2-multiple').select2MultiCheckboxes({
placeholder: "Choose multiple elements",
})
http://jsfiddle.net/wasikuss/gx93rwnk/
All other features of select2 are preserved. There are few more predefined options set to work properly.
I managed to put something together, not perfect, but it works.
https://jsfiddle.net/Lkkm2L48/7/
jQuery(function($) {
$.fn.select2.amd.require([
'select2/selection/single',
'select2/selection/placeholder',
'select2/selection/allowClear',
'select2/dropdown',
'select2/dropdown/search',
'select2/dropdown/attachBody',
'select2/utils'
], function (SingleSelection, Placeholder, AllowClear, Dropdown, DropdownSearch, AttachBody, Utils) {
var SelectionAdapter = Utils.Decorate(
SingleSelection,
Placeholder
);
SelectionAdapter = Utils.Decorate(
SelectionAdapter,
AllowClear
);
var DropdownAdapter = Utils.Decorate(
Utils.Decorate(
Dropdown,
DropdownSearch
),
AttachBody
);
var base_element = $('.select2-multiple2')
$(base_element).select2({
placeholder: 'Select multiple items',
selectionAdapter: SelectionAdapter,
dropdownAdapter: DropdownAdapter,
allowClear: true,
templateResult: function (data) {
if (!data.id) { return data.text; }
var $res = $('<div></div>');
$res.text(data.text);
$res.addClass('wrap');
return $res;
},
templateSelection: function (data) {
if (!data.id) { return data.text; }
var selected = ($(base_element).val() || []).length;
var total = $('option', $(base_element)).length;
return "Selected " + selected + " of " + total;
}
})
});
});
CSS:
.select2-results__option .wrap:before{
font-family:fontAwesome;
color:#999;
content:"\f096";
width:25px;
height:25px;
padding-right: 10px;
}
.select2-results__option[aria-selected=true] .wrap:before{
content:"\f14a";
}
Add just two emoji with css
.select2-results__options {
&[aria-multiselectable=true] {
.select2-results__option {
&[aria-selected=true]:before {
content: '☑';
padding: 0 0 0 4px;
}
&:before {
content: '◻';
padding: 0 0 0 4px;
}
}
}
}
You see this sample a RTL select2 with emoji based checkbox
Here is very simple snippet, without strange modyfing of js - pure and simple css (with "Font Awesome")
$('.select2[multiple]').select2({
width: '100%',
closeOnSelect: false
})
#body{
padding: 30px
}
.select2-results__options[aria-multiselectable="true"] li {
padding-left: 30px;
position: relative
}
.select2-results__options[aria-multiselectable="true"] li:before {
position: absolute;
left: 8px;
opacity: .6;
top: 6px;
font-family: "FontAwesome";
content: "\f0c8";
}
.select2-results__options[aria-multiselectable="true"] li[aria-selected="true"]:before {
content: "\f14a";
}

Now the code is ready to use for you to implement the multiple checkboxes select2 dropdown.
Enjoy :)

<p>Here, you can select any item by clicking on row or checked in on checkbox and can unselect in reverse way.</p>
<p>But I didn't give the option to select "SelectAll" option by clicking on his row, you can select-all and unselect-all by click on checkbox only rather than row.</p>

Another workaround is to "prepend" checkbox icons using CSS. I use bootstrap theme - your select2-container may be different.
.select2-container--bootstrap .select2-results__option[aria-selected=true]:before { content:'\e067 '; padding:0 8px 0 0px; font-family:'Glyphicons Halflings' }
.select2-container--bootstrap .select2-results__option:before { content:'\e157 '; padding:0 8px 0 0px; font-family:'Glyphicons Halflings' }

jQuery UI combobox does not render correctly in IE 9.x?

I have a html page based on Combobox autocomplete demo at Combobox jQuery Autocomplete Demo. The problem is that the combobox renders perfectly in FireFox 13.x. However, in IE 9.x (64-bit), it does the autocomplete part correctly, but is strange in appearance as you can see at this link: Strange jQuery Combobox Appearance in IE 9.x. I thought jQuery was the perfect cross-browser technology, but it doesn't look like it. Or may be I am missing something in my html code? The complete html code is as given below.

I just found the issue that was causing incorrect rendering in IE. For things to render properly in IE, when using jQuery, you must specify doc type as in code below. That will make the jQuery combobox render properly in IE.
<!DOCTYPE html>

<head>
<meta charset="utf-8">

<link type="text/css" href="css/cupertino/jquery-ui-1.8.21.custom.css" rel="stylesheet" />

<script type="text/javascript" src="js/jquery-ui-1.8.21.custom.min.js"></script>
You could, as an alternate, also use the following web URLs to get the css and scripts related to jQuery in this example, rather than the local URLs that were mentioned in above code sample.
