I have created a multiselect dropdown using Bootstrap Multiselect . I need to set a limit in options selection (Here I set it to 5) and if the limit reached I just disabled the other select optons and it Works Perfectly. But the problem is When I tried to select more than 5 using SHIFT key. It doesn't work(means my jQuery to prevent selection not work) and I can select more than 5. Please Check the Snippet and give me a solution.

JSFIDDLE

 jQuery('#soft_skill_list').multiselect({
        enableFiltering: true,
        maxHeight:400,
        enableCaseInsensitiveFiltering:true, 
        nonSelectedText: 'Soft Skills *', 
        numberDisplayed: 2, 
        selectAll: false, 
        onChange: function(option, checked) {
                // Get selected options.
                var selectedOptions = jQuery('#soft_skill_list option:selected');
 
                if (selectedOptions.length >= 5) {
                    // Disable all other checkboxes.
                    var nonSelectedOptions = jQuery('#soft_skill_list option').filter(function() {
                        return !jQuery(this).is(':selected');
                    });
 
                    nonSelectedOptions.each(function() {
                        var input = jQuery('input[value="' + jQuery(this).val() + '"]');
                        input.prop('disabled', true);
                        input.parent('li').addClass('disabled');
                    });
                }
                else {
                    // Enable all checkboxes.
                    jQuery('#soft_skill_list option').each(function() {
                        var input = jQuery('input[value="' + jQuery(this).val() + '"]');
                        input.prop('disabled', false);
                        input.parent('li').addClass('disabled');
                    });
                }
            }});

If you have more than one multiselect in the same page with the same option value, make sure that you add the correct selector function when you are enabling/disabling the checkboxes, you have to replace this line

    var input = jQuery('input[value="' + jQuery(this).val() + '"]');

for this

    var input = jQuery('#soft_skill_list + .btn-group input[value="' + jQuery(this).val() + '"]');

Otherwise you will be disabling other checkboxes in the other multiselect controls as well.

I will be it like this:

jQuery('#soft_skill_list').multiselect({
    enableFiltering: true,
    maxHeight:400,
    enableCaseInsensitiveFiltering:true, 
    nonSelectedText: 'Soft Skills *', 
    numberDisplayed: 2, 
    selectAll: false, 
    onChange: function(option, checked) {
            // Get selected options.
            var selectedOptions = jQuery('#soft_skill_list option:selected');

            if (selectedOptions.length >= 5) {
                // Disable all other checkboxes.
                var nonSelectedOptions = jQuery('#soft_skill_list option').filter(function() {
                    return !jQuery(this).is(':selected');
                });

                nonSelectedOptions.each(function() {
                    var input = jQuery('#soft_skill_list + .btn-group input[value="' + jQuery(this).val() + '"]');
                    input.prop('disabled', true);
                    input.parent('li').addClass('disabled');
                });
            }
            else {
                // Enable all checkboxes.
                jQuery('#soft_skill_list option').each(function() {
                    var input = jQuery('#soft_skill_list + .btn-group  input[value="' + jQuery(this).val() + '"]');
                    input.prop('disabled', false);
                    input.parent('li').addClass('disabled');
                });
            }
        }});
