How to use Checkbox inside Select Option

2018-06-27 03:06:31

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.

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.

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>

The best plugin so far is Bootstrap Multiselect

<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 the DEMO

Try multiple-select. Looks to be much clean and managed solution, with tons of examples.
