jquery MultiSelect CheckBox

jQuery MultiSelect

Turn a multiselect list into a nice and easy to use list with checkboxes. This plugin is simply an alternative interface for the native select list element. When you check an option in the plugin the value is selected on the native list. This allows the value to be submitted in a form as well as retreived through normal POST/GET and javascript methods.

Support

I only provide limited support through the Github Issues area. DO NOT ask for support via email, socialmedia, or other means. Also check the closed issues before opening a new issue.

Design Methodology

This plugin is not meant to be a full featured multiselect plugin. I envision this as a multiselect plugin that contains a base set of features that can be enhanced using callbacks by the developer. Because of this I am hesitant on adding functionality but am open to adding callbacks where it makes sense. But feel free to open an issue and suggest a feature request if you feel that most people will benefit from it.

Usage

// BASIC
$('select[multiple]').multiselect();

// 4 COLUMNS with custom placeholder text
$('select[multiple]').multiselect({
    columns: 4,
    texts: {
        placeholder: 'Select options'
    }
});

// RELOAD multiselect (in case you modify options or selected options in the native select list since loading the plugin)
$('select[multiple]').multiselect('reload');

// DYNAMICALLY LOAD OPTIONS
$('select[multiple]').multiselect( 'loadOptions', [{
    name   : 'Option Name 1',
    value  : 'option-value-1',
    checked: false,
    attributes : {
        custom1: 'value1',
        custom2: 'value2'
    }
},{
    name   : 'Option Name 2',
    value  : 'option-value-2',
    checked: false,
    attributes : {
        custom1: 'value1',
        custom2: 'value2'
    }
}]);

Methods

loadOptions( options, overwrite, updateSelect )

Update options of select list. Default state will replace existing list with this one.

Set the second parameter to false to append to the list. (default = true)
Set the third parameter to false to leave the native select list as is. (default = true)

This will NOT modify the original select list element.

$('select[multiple]').multiselect( 'loadOptions', [{
    name   : 'Option Name 1',
    value  : 'option-value-1',
    checked: false
},{
    name   : 'Option Name 2',
    value  : 'option-value-2',
    checked: false
}]);

settings

Update Multiselect list settings after it has been rendered. It accepts the same options listed above.

This will reload the plugin for the select list it references

$('select[multiple]').multiselect( 'settings', { columns: 2 });

unload

Disable the jquery multiselect list and show the native select list.

This is distructive. You will have to reinitialize with all options to enable the plugin for the list.

$('select[multiple]').multiselect( 'unload' );

reload

This is a quick unload/load while maintaining options during plugin initialization.

$('select[multiple]').multiselect( 'reload' );

reset

Reset the element back to its default selected values.

$('select[multiple]').multiselect( 'reset' );

disable

Disable or enable the select list. If no second parameter is passed then true is assumed.

$('select[multiple]').multiselect( 'disable', true ); $('select[multiple]').multiselect( 'disable', false );
