I am utilizing the Bootstrap Dual Listbox plugin to assist users in selecting specific options.
I have successfully integrated this plugin into my project. However, I encountered an issue when attempting to impose a limit on the number of options a user can choose.
For instance, consider the following options:
- Apple
- Mango
- Orange
- Melon
- Guava
In this scenario, users must select exactly 3 options and cannot choose options 1, 2, 4, or 5.
The problem revolves around restricting the number of options that can be chosen. By default, users are not confined by any limitations.
Here is a segment of my code:
<script src="<?php echo $baseurl; ?>assets/js/plugins/dual/dist/jquery.bootstrap-duallistbox.js"></script>
<link href="<?php echo $baseurl; ?>assets/js/plugins/dual/dist/bootstrap-duallistbox.css" rel="stylesheet" type="text/css" media="all">
<div id="addimeiform" class="box-content form-horizontal">
<select multiple="multiple" id="imei_multi" name="duallistbox_demo1">
<?php
while ($row = mysql_fetch_array($query)) {
echo "<option>".$row['imei']."</option>";
}
?>
</select>
</div>
<script>
var demo1 = $('[name=duallistbox_demo1]').bootstrapDualListbox();
</script>
