How to use Checkbox inside Select Option

The client has given me a design which has a Select Option menu containing a checkbox together with the item name as individual items in the list. Is there anyway possible to add a checkbox inside a Select Option menu?

NB: Developer needs to add his own id to make the menu effective, I only need the HTML CSS code if it is possible.

The best plugin so far is Bootstrap Multiselect

EDIT: I wrote this a very long time ago. I would not recommend using jQuery anymore. You should rather learn a reactive framework like Vue.js, React, or Angular where you have plenty of modules to choose from. I'm sure you'll find what you need. I found this one for instance from a quick Google search.

<html xmlns="http://www.w3.org/1999/xhtml">
<head>

<title>jQuery Multi Select Dropdown with Checkboxes</title>

<link rel="stylesheet" href="css/bootstrap-3.1.1.min.css" type="text/css" />
<link rel="stylesheet" href="css/bootstrap-multiselect.css" type="text/css" />

<script type="text/javascript" src="http://code.jquery.com/jquery-1.8.2.js"></script>
<script type="text/javascript" src="js/bootstrap-3.1.1.min.js"></script>
<script type="text/javascript" src="js/bootstrap-multiselect.js"></script>

</head>

<body>

<form id="form1">

<div style="padding:20px">

<select id="chkveg" multiple="multiple">
    
    <option value="cheese">Cheese</option>
    <option value="tomatoes">Tomatoes</option>
    <option value="mozarella">Mozzarella</option>
    <option value="mushrooms">Mushrooms</option>
    <option value="pepperoni">Pepperoni</option>
    <option value="onions">Onions</option>

</select>

<br /><br />

<input type="button" id="btnget" value="Get Selected Values" />

<script type="text/javascript">

$(function() {
    
    $('#chkveg').multiselect({
        
        includeSelectAllOption: true
    });
    
    $('#btnget').click(function(){
        
        alert($('#chkveg').val());
    });
});

</script>

</div>

</form>

</body>
</html>

Here's a demo:

$(function() {

  $('#chkveg').multiselect({
    includeSelectAllOption: true
  });

  $('#btnget').click(function() {
    alert($('#chkveg').val());
  });
});
.multiselect-container>li>a>label {
  padding: 4px 20px 3px 20px;
}
<link href="https://unpkg.com/[email protected]/dist/css/bootstrap.min.css" rel="stylesheet"/>
<script src="https://unpkg.com/[email protected]/dist/jquery.min.js"></script>
<script src="https://unpkg.com/[email protected]/dist/js/bootstrap.min.js"></script>
<script src="https://unpkg.com/[email protected]/dist/js/bootstrap-multiselect.js"></script>
<link href="https://unpkg.com/[email protected]/dist/css/bootstrap-multiselect.css" rel="stylesheet"/>

<form id="form1">
  <div style="padding:20px">

    <select id="chkveg" multiple="multiple">
      <option value="cheese">Cheese</option>
      <option value="tomatoes">Tomatoes</option>
      <option value="mozarella">Mozzarella</option>
      <option value="mushrooms">Mushrooms</option>
      <option value="pepperoni">Pepperoni</option>
      <option value="onions">Onions</option>
    </select>
    
    <br /><br />

    <input type="button" id="btnget" value="Get Selected Values" />
  </div>
</form>

Try multiple-select, especially multiple-items. Looks to be much clean and managed solution, with tons of examples. You can also view the source.

<div>
  <div class="form-group row">
    <label class="col-sm-2">
      Basic Select
    </label>

    <div class="col-sm-10">
      <select multiple="multiple">
        <option value="1">1</option>
        <option value="2">2</option>
      </select>
    </div>
  </div>

  <div class="form-group row">
    <label class="col-sm-2">
      Group Select
    </label>

    <div class="col-sm-10">
      <select multiple="multiple">
        <optgroup label="Group 1">
          <option value="1">1</option>
          <option value="2">2</option>
        </optgroup>
        <optgroup label="Group 2">
          <option value="6">6</option>
          <option value="7">7</option>
        </optgroup>
        <optgroup label="Group 3">
          <option value="11">11</option>
          <option value="12">12</option>
        </optgroup>
      </select>
    </div>
  </div>
</div>

<script>
  $(function() {
    $('select').multipleSelect({
      multiple: true,
      multipleWidth: 60
    })
  })
</script>

If you want to create multiple select dropdowns in the same page:

.multiselect {
  width: 200px;
}

.selectBox {
  position: relative;
}

.selectBox select {
  width: 100%;
  font-weight: bold;
}

.overSelect {
  position: absolute;
  left: 0;
  right: 0;
  top: 0;
  bottom: 0;
}

#checkboxes {
  display: none;
  border: 1px #dadada solid;
}

#checkboxes label {
  display: block;
}

#checkboxes label:hover {
  background-color: #1e90ff;
}

Html:

 <form>
<div class="multiselect">
<div class="selectBox" onclick="showCheckboxes()">
<select>
<option>Select an option</option>
</select>
<div class="overSelect"></div>
</div>
<div id="checkboxes">
<label for="one">
<input type="checkbox" id="one" />First checkbox</label>
<label for="two">
<input type="checkbox" id="two" />Second checkbox</label>
<label for="three">
<input type="checkbox" id="three" />Third checkbox</label>
</div>
</div>
<div class="multiselect">
<div class="selectBox" onclick="showCheckboxes()">
<select>
<option>Select an option</option>
</select>
<div class="overSelect"></div>
</div>
<div id="checkboxes">
<label for="one">
<input type="checkbox" id="one" />First checkbox</label>
<label for="two">
<input type="checkbox" id="two" />Second checkbox</label>
<label for="three">
<input type="checkbox" id="three" />Third checkbox</label>
</div>
</div>

</form>

Using Jquery:

 function showCheckboxes(elethis) {
        if($(elethis).next('#checkboxes').is(':hidden')){
            $(elethis).next('#checkboxes').show();
            $('.selectBox').not(elethis).next('#checkboxes').hide();  
        }else{
            $(elethis).next('#checkboxes').hide();
            $('.selectBox').not(elethis).next('#checkboxes').hide();
        }
 }

Alternate Vanilla JS version with click outside to hide checkboxes:

let expanded = false;
const multiSelect = document.querySelector('.multiselect');

multiSelect.addEventListener('click', function(e) {
  const checkboxes = document.getElementById("checkboxes");
    if (!expanded) {
    checkboxes.style.display = "block";
    expanded = true;
  } else {
    checkboxes.style.display = "none";
    expanded = false;
  }
  e.stopPropagation();
}, true)

document.addEventListener('click', function(e){
  if (expanded) {
    checkboxes.style.display = "none";
    expanded = false;
  }
}, false)

I'm using addEventListener instead of onClick in order to take advantage of the capture/bubbling phase options along with stopPropagation(). You can read more about the capture/bubbling here: https://developer.mozilla.org/en-US/docs/Web/API/EventTarget/addEventListener

The rest of the code matches vitfo's original answer (but no need for onclick() in the html). A couple of people have requested this functionality sans jQuery.

Here's codepen example https://codepen.io/davidysoards/pen/QXYYYa?editors=1010

I started from @vitfo answer but I want to have <option> inside <select> instead of checkbox inputs so i put together all the answers to make this, there is my code, I hope it will help someone.

$(".multiple_select").mousedown(function(e) {
    if (e.target.tagName == "OPTION") 
    {
      return; //don't close dropdown if i select option
    }
    $(this).toggleClass('multiple_select_active'); //close dropdown if click inside <select> box
});
$(".multiple_select").on('blur', function(e) {
    $(this).removeClass('multiple_select_active'); //close dropdown if click outside <select>
});
	
$('.multiple_select option').mousedown(function(e) { //no ctrl to select multiple
    e.preventDefault(); 
    $(this).prop('selected', $(this).prop('selected') ? false : true); //set selected options on click
    $(this).parent().change(); //trigger change event
});

	
	$("#myFilter").on('change', function() {
      var selected = $("#myFilter").val().toString(); //here I get all options and convert to string
      var document_style = document.documentElement.style;
      if(selected !== "")
        document_style.setProperty('--text', "'Selected: "+selected+"'");
      else
        document_style.setProperty('--text', "'Select values'");
	});
:root
{
	--text: "Select values";
}
.multiple_select
{
	height: 18px;
	width: 90%;
	overflow: hidden;
	-webkit-appearance: menulist;
	position: relative;
}
.multiple_select::before
{
	content: var(--text);
	display: block;
  margin-left: 5px;
  margin-bottom: 2px;

Use this code for checkbox list on option menu.

.dropdown-menu input {
   margin-right: 10px;
}   
<div class="btn-group">
    <a href="#" class="btn btn-primary"><i class="fa fa-cogs"></i></a>
    <a href="#" class="btn btn-primary dropdown-toggle" data-toggle="dropdown">
      <span class="caret"></span>
    </a>
    <ul class="dropdown-menu" style="padding: 10px" id="myDiv">
        <li><p><input type="checkbox" value="id1" > OA Number</p></li>
        <li><p><input type="checkbox" value="id2" >Customer</p></li>
        <li><p><input type="checkbox" value="id3" > OA Date</p></li>
        <li><p><input type="checkbox" value="id4" >Product Code</p></li>
        <li><p><input type="checkbox" value="id5" >Name</p></li>
        <li><p><input type="checkbox" value="id6" >WI Number</p></li>
        <li><p><input type="checkbox" value="id7" >WI QTY</p></li>
        <li><p><input type="checkbox" value="id8" >Production QTY</p></li>
        <li><p><input type="checkbox" value="id9" >PD Sr.No (from-to)</p></li>
        <li><p><input type="checkbox" value="id10" > Production Date</p></li>
        <button class="btn btn-info" onClick="showTable();">Go</button>
    </ul>

You can use this library on git for this purpose https://github.com/ehynds/jquery-ui-multiselect-widget

for initiating the selectbox use this

    $("#selectBoxId").multiselect().multiselectfilter();

and when you have the data ready in json (from ajax or any method), first parse the data & then assign the js array to it

    var js_arr = $.parseJSON(/*data from ajax*/);
    $("#selectBoxId").val(js_arr);
    $("#selectBoxId").multiselect("refresh");

You cannot place checkbox inside select element but you can get the same functionality by using HTML, CSS and JavaScript. Here is a possible working solution. The explanation follows.

enter image description here

Code:

var expanded = false;

function showCheckboxes() {
  var checkboxes = document.getElementById("checkboxes");
  if (!expanded) {
    checkboxes.style.display = "block";
    expanded = true;
  } else {
    checkboxes.style.display = "none";
    expanded = false;
  }
}
.multiselect {
  width: 200px;
}

.selectBox {
  position: relative;
}

.selectBox select {
  width: 100%;
  font-weight: bold;
}

.overSelect {
  position: absolute;
  left: 0;
  right: 0;
  top: 0;
  bottom: 0;
}

#checkboxes {
  display: none;
  border: 1px #dadada solid;
}

#checkboxes label {
  display: block;
}

#checkboxes label:hover {
  background-color: #1e90ff;
}
<form>
  <div class="multiselect">
    <div class="selectBox" onclick="showCheckboxes()">
      <select>
        <option>Select an option</option>
      </select>
      <div class="overSelect"></div>
    </div>
    <div id="checkboxes">
      <label for="one">
        <input type="checkbox" id="one" />First checkbox</label>
      <label for="two">
        <input type="checkbox" id="two" />Second checkbox</label>
      <label for="three">
        <input type="checkbox" id="three" />Third checkbox</label>
    </div>
  </div>
</form>

Explanation:

At first we create a select element that shows text "Select an option", and empty element that covers (overlaps) the select element (<div class="overSelect">). We do not want the user to click on the select element - it would show an empty options. To overlap the element with other element we use CSS position property with value relative | absolute.

To add the functionality we specify a JavaScript function that is called when the user clicks on the div that contains our select element (<div class="selectBox" onclick="showCheckboxes()">).

We also create div that contains our checkboxes and style it using CSS. The above mentioned JavaScript function just changes <div id="checkboxes"> value of CSS display property from "none" to "block" and vice versa.

The solution was tested in the following browsers: Internet Explorer 10, Firefox 34, Chrome 39. The browser needs to have JavaScript enabled.

For a Pure CSS approach, you can use the :checked selector combined with the ::before selector to inline conditional content.

Just add the class select-checkbox to your select element and include the following CSS:

.select-checkbox option::before {
  content: "\2610";
  width: 1.3em;
  text-align: center;
  display: inline-block;
}
.select-checkbox option:checked::before {
  content: "\2611";
}

You can use plain old unicode characters (with an escaped hex encoding) like these:

Or if you want to spice things up, you can use these FontAwesome glyphs

Screenshot

Demo in jsFiddle & Stack Snippets

select {
  width: 150px;
}

.select-checkbox option::before {
  content: "\2610";
  width: 1.3em;
  text-align: center;
  display: inline-block;
}
.select-checkbox option:checked::before {
  content: "\2611";
}

.select-checkbox-fa option::before {
  font-family: FontAwesome;
  content: "\f096";
  width: 1.3em;
  display: inline-block;
  margin-left: 2px;
}
.select-checkbox-fa option:checked::before {
  content: "\f046";
}
<link rel="stylesheet" type="text/css" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.css">

<h3>Unicode</h3>
<select multiple="" class="form-control select-checkbox" size="5">
  <option>Dog</option>
  <option>Cat</option>
  <option>Hippo</option>
  <option>Dinosaur</option>
  <option>Another Dog</option>
</select>

<h3>Font Awesome</h3>

  <option>Another Dog</option>
</select>

Note: Beware of IE compatibility issues however

You might be loading multiselect.js file before the option list updated with AJAX call so while execution of multiselect.js file there is empty option list is there to apply multiselect functionlaity. So first update the option list by AJAX call then initiate the multiselect call you will get the dropdown list with the dynamic option list.

Hope this will help you out.

Multiselect dropdown list and related js & css files

// This function should be called while loading page
var loadParentTaskList = function(){
    $.ajax({
        url: yoururl,
        method: 'POST',
        success: function(data){
            // To add options list coming from AJAX call multiselect
            for (var field in data) {
                $('<option value = "'+ data[field].name +'">' + data[field].name + '</option>').appendTo('#parent_task');
            }
   
            // To initiate the multiselect call 
            $("#parent_task").multiselect({
                includeSelectAllOption: true
            })
        }
    });
}
// Multiselect drop down list with id parent_task
<select id="parent_task" multiple="multiple">
</select>
