This plugin allows you to add a sweet treeview frontend to a select element. The underlying select element can be used as it was before.


My website has a simple demo running.



Make sure your select has the multiple attribute set. Also, make sure you've got <meta charset="UTF-8"> or some of the symbols may look strange.

Option Attribute name Description
selected Have the option pre-selected. This is actually part of the HTML spec
data-section The section the option will be in; can be nested
data-description A description of the attribute; will be shown on the multiselect
data-index For pre-selected options, display options in this order, lowest index first. Conflicts will be overwritten by the last item with the same data-index

All of the above are optional.

Your data-section can have multiple section names, separated by the sectionDelimiter option.

Ex. data-section="top/middle/inner" will show up as - top - middle - inner - your option


You can pass in params like treeMultiselect(params). It is an object where you can set the following features:

Name Default Description
allowBatchSelection true Sections have checkboxes which when checked, check everything within them
collapsible true Adds collapsibility to sections
enableSelectAll false Enables selection of all or no options
selectAllText Select All Only used if enableSelectAll is active
unselectAllText Unselect All Only used if enableSelectAll is active
freeze false Disables selection/deselection of options; aka display-only
hideSidePanel false Hide the right panel showing all the selected items
onChange null Callback for when select is changed. Called with (allSelectedItems, addedItems, removedItems), each of which is an array of objects with the properties text, value, initialIndex, and section
onlyBatchSelection false Only sections can be checked, not individual items
sortable false Selected options can be sorted by dragging (requires jQuery UI)
searchable false Allows searching of options
searchParams ['value', 'text', 'description', 'section'] Set items to be searched. Array must contain 'value', 'text', or 'description', and/or 'section'
sectionDelimiter / Separator between sections in the select option data-section attribute
showSectionOnSelected true Show section name on the selected items
startCollapsed false Activated only if collapsible is true; sections are collapsed initially


Load jquery.tree-multiselect.min.js on to your web page. The css file is optional (but recommended).

You can also use bower - bower install tree-multiselect


Help! The first element is selected when I create the tree. How do I make the first element not selected? You didn't set the multiple attribute on your select. This is a property of single-option select nodes - the first option is selected.

How do I dynamically change ___? Not supported... yet.
