jQuery Plugin For Multi-Selectable Tree Structure - Tree Multiselect

Tree Multiselect is a jQuery plugin that converts a multiple select box into a collapsible tree view with checkboxes for easy option selection. The user can either delete a selection from selected items in expanded view or by unchecking a select option.

Installation:

# Yarn
$ yarn add tree-multiselect

# NPM
$ npm install tree-multiselect --save

How to use it:

1. Include jQuery library and the jQuery tree multiselect plugin's JS & CSS files on your html page.

<link href="jquery.tree-multiselect.min.css" rel="stylesheet">
<script src="//code.jquery.com/jquery-1.11.3.min.js"></script>
<script src="jquery.tree-multiselect.min.js"></script>

2. Include jQuery UI library for drag and drop support.

<script src="//code.jquery.com/ui/1.11.4/jquery-ui.min.js"></script>

3. Create a multiple select and use data-section to specify the hierarchical structure for each option.

<select id="demo" multiple="multiple">
  <option value="one" data-section="top" selected="selected" data-index="3">C++</option>
  <option value="two" data-section="top" selected="selected" data-index="1">Python</option>
  <option value="three" data-section="top" selected="selected" data-index="2">Ruby</option>
  <option value="four" data-section="top">Swift</option>
  <option value="wow" data-section="JavaScript/Library/Popular">jQuery</option>
</select>

4. Initialize the plugin.

$("#demo").treeMultiselect(options);

5. Possible plugin options.

$("#demo").treeMultiselect({

  // Sections have checkboxes which when checked, check everything within them
  allowBatchSelection: true,

  // Selected options can be sorted by dragging 
  // Requires jQuery UI
  sortable: false,

  // Adds collapsibility to sections
  collapsible: true,

  // Enables selection of all or no options
  enableSelectAll: false,

  // Only used if enableSelectAll is active
  selectAllText: 'Select All',

  // Only used if enableSelectAll is active
  unselectAllText: 'Unselect All',

  // Disables selection/deselection of options; aka display-only
  freeze: false,

  // Hide the right panel showing all the selected items
  hideSidePanel: false,

  // max amount of selections
  maxSelections: 0,

  // Only sections can be checked, not individual items
  onlyBatchSelection: false,

  // Separator between sections in the select option data-section attribute
  sectionDelimiter: '/',

  // Show section name on the selected items
  showSectionOnSelected: true,

  // Activated only if collapsible is true; sections are collapsed initially
  startCollapsed: false,

  // Allows searching of options
  searchable: false,

  // Set items to be searched. Array must contain 'value', 'text', or 'description', and/or 'section'
  searchParams: ['value', 'text', 'description', 'section'],

  // Callback

});
