Jquery bootstrap multiselect optgroup selection

Question

I am using Jquery bootstrap multiselect plugin which seems pretty good and fulfill most of the requirements which i needed.

The only additional functionality i want is to add checkbox to OptGroup so if user wants to select complete group they can select all by clicking it.

any help appreciated.

Solution 1

Try something like this:

$('.multiselect-group').before('<input type="checkbox" />');
$(document).on('click', '.multiselect-group', function(event) {
    var checkAll = true;
    var $opts = $(this).parent().nextUntil(':has(.multiselect-group)'); 
    var $inactive = $opts.filter(':not(.active)'); 
    var $toggleMe = $inactive;
    if ($inactive.length == 0) { 
        $toggleMe = $opts;
        checkAll = false;
    }
    $toggleMe.find('input').click();
    $(this).parent().find('input').attr('checked', checkAll);
    event.preventDefault();
});

Solution 2

No need to do any code to achieve your requirement.

There is an option called enableClickableOptGroups in this plugin to select all options of optgroup

Solution 3

You can use event.stopPropagation();

Solution 4

After I checked an option group and then unchecked it, if I wanted to check it again, it would check all options from the group, but the group remained unchecked.

In order for the option group to be properly displayed as checked/unchecked after several retries, replace:

$(this).parent().find('input').**attr**('checked', checkAll);

with

$(this).parent().find('input').**prop**('checked', checkAll);

It works well only i can tweak the UI to look adjust checkbox alignment. the only problem is if you select optgroup checkbox drop down automatically gets close. any work around ?

I believe that is from the click event handler on the list parent. Use event.preventDefault(). I'll update the answer to show this.

if you click on opt group label it does check all childs but still hiding drop down.
