type: URL, required: yes, default: -

The endpoint to use, e.g. http://your.celum.server/anura/first


type: String, required: no, default: CELUM's default language

The locale (ISO 639-1) to use, i.e. en. The availability of these depend on your CELUM configuration, usually en, de or fr. When left empty, CELUM's default language will be used.


type: Object, required: yes, default: {kind: 101, id: 0}

The root node of your tree, i.e. {kind: 103, id: 1337}. Note that since CELUM 5, the kind-parameter is no longer required unless you set the ID to -1.


type: long, required: seldom, default: 101

The NodeTypeId of the desired node. Traditionally folder = 101, collection = 102 and keywords = 103, but check your tabconfiguration.xml to be sure. Since CELUM 5 this is only required when you set the to -1.

type: long or array of longs, required: if node is specified, default: 0

The NodeId of the root node(s). Also supports arrays, i.e. you can construct a "virtual root node" (to aggregate multiple nodes from different locations) by using {kind: ..., id: [1, 2, 3]}. Can also be set to -1 to get all root nodes as long as a kind is provided (enforces show_root=true; since 1.7).


type: boolean, required: no, default: false

Also show the root node(s) themselves (usually only the child nodes are shown). Probably only useful for virtual root nodes.


type: mixed, required: no, default: false

What to show after the tree has been loaded (triggers an attached main view). One of:

  • 'first' or true - show the first leaf node in the tree
  • 'last' - show the last leaf node in the tree
  • 4123 - an arbitrary ID of a node in the tree

type: int, required no, default: 0

Depth to which the tree should be loaded (lazy loading). A depth smaller than one loads the entire tree.


type: String, required: no, default: ''

Prefix for the state fragment in the URL (only needed for multi-instance). Set to false to completely disable state (deep linking through updating the URL fragment)


type: boolean, required: no, default: false

If the number of assets in each node should be shown. Has some persormance implications for large trees, as every subnode has to be queried individually. Note that if you're using noderef in your main view, you need to also configure noderef: true here for consistent results.


type: boolean, required: no, default: false

Whether to hide nodes that have an asset_count of 0. Setting this to true automatically sets asset_count: true.


type: function or String, required: no, default: null

How the tree should be sorted (per level). Can be either one of id_asc, name_asc, info_asc (or ..._desc) of a custom comparison function, see MDN


type: function, required: I'd recommend it, default: see below

What should happen when a user clicks on a node in the tree. By default it tries to find the next best gallery component:

callback: function(server, kind, id, name) {
    $('.anura-gallery-container').first().parent().anuraGallery({server: server, assets: null, node: {kind: kind, id: id}});

If you don't use the gallery or want to be more efficient about it, your code will look something like:

var mainView = $('#your-main-view').anuraMasonry({...});
var tree = $('#your-tree').anuraTree({
    /*... other settings ... */
    callback: function(server, kind, id, name) {
        mainView.anuraMasonry({server: server, assets: null, node: {kind: kind, id: id}});

type: boolean, required: no, default: true

Whether to show the node state (● has subnodes, ○ has no subnodes, ■ lazy loaded) through list styles (since 2.2)


type: boolean, required: no, default: false

Enable folding of the tree (regardless of the current selection) when clicking on the list style icons since 2.3


type: String, required: no, default: null

Adds a custom href attribute to each item in the tree. This is an alternative to the callback, but it's not compatible with the _state_option. since 2.6


type: boolean, required: no, default: false

Enables multi-select on the tree (through CTRL). This is probably only useful then used inside anuraSearch. since 2.7


  • anuraTree can also be used as a horizontal navigation bar (with folding). Simply use jquery.anura.navbar.css instead of jquery.anura.tree.css (suitable for trees up to a depth of 3)
  • Do not initialize the tree before the gallery component when using the show parameter or the URL-state, as this may lead to a race condition


  • anura-loaded (options, data) - triggered when the plugin has loaded all nodes
  • anura-clicked (server, kind, id, name) - triggered when a user clicks on a node/leaf
  • anura-reset - triggered when reset via anuraSearch


<div class="anura-tree-container">
      <li class="anura-node anura-active">
         <a><span class="anura-node-name">Parent Node</span></a>
         <ul class="anura-tree-unfolded">
            <li class="anura-node">
               <a><span class="anura-node-name">Child Node</span></a>
               <ul class="anura-tree-folded">
            <li class="anura-leaf">
               <a><span class="anura-node-name">Child Leaf</span></a>

requires backend version 1.5 or higher

Name Example Default Comment
locale 'de' -
widgets [{name: 'text', scope: $('#navigation')}] - Which search components to show and in what order. See widget options.
callback function(server, search_query) {/*do something*/} (see below) Function defining the action to be triggered when clicking on a node. If no function has been specified the plugin will look for an existing gallery to show the contents of the node
folder 42 - DEPRECATED (use custom=). Restrict search to this folder - widget.scope overrides this if enabled
keyword 7 - DEPRECATED (use custom=). Restrict search to this keyword - widget.scope or keywords override this if enabled
custom search_infofield=628,1 - Arbitrary string argument sent along with the request (see API search parameters for details). Since 2.9 you can also define a function that returns said string.
resettable false true Adds a reset search link to the bottom
show_empty true false Whether to tell the attached view about the lack of search results (otherwise just show a message in search, 1.x only)
extended true false Request extended asset properties (size, modified) etc. - has no effect other than that you could use them for sorting
container_class 'my-class' '' custom class to be added to every widget container div
facets true false enable faceted search on the widgets - requires corresponding configuration of the back-end - since 2.6
initial_search false | true | triggers an initial search as soon as the component is loaded, so the user can see something (recommended when facets is enabled) - since 2.7
fallback_search search_node=123 null what to search for when the user hasn't selected anything, useful for an "welcome view" (see API search parameters for details) - since 2.8
Widget Options
{name: 'text', scope: null, resettable: false}, // scope needs an anuraTree of folders or keywords, e.g. $('#navigation'); resettable adds an 'x' to clear the text
{name: 'filetype', style: optional string}, // document type (images, documents, audio, video, others), style: checkbox/dropdown/select
{name: 'assettype', style: optional string}, // asset type (as defined by your infofields.xml), style: checkbox/radio/dropdown/select
{name: 'keywords', root: keyword id, multiple: bool, show: optional keyword id} // requires jquery.anura.tree (works for any node type in 2.0+)
{name: 'infofield', id: infofield id, style: optional string} // style: dropdown/select/checkbox/radio/tree (availability depends on infofield type)
{name: 'submit', show: true, resettable: true}
  • autosubmit is available on all widgets, set this to true in order to trigger the search immediately (instead of waiting for the "search"-button to be clicked)
  • title may be specified on every widget in order to override the default, either title: "Foo" or title: {de: "Foo", en: "Bar"}
  • container_class to override the global container_class-setting on this widget
  • tree-containing widgets (keyword, noderef infofield) support a tree_settings-parameter where you can specify additional anuraTree-options that will be applied to the inner tree.
  • node-referencing infofields can enable and_mode: true to search with AND within the same field (instead of the default OR), and recursive: false to disable node recursion (i.e. only accept this exact node). The dropdown-variants also support sort (false, 'asc' (default), 'desc' or a custom sort function).
  • text-fields provide a type-ahead datalist when using facets, use datalist: false to disable it.

If you include chosen, all dropdown and multi-select fields will automatically use it.


  • The default callback tries to find the next best gallery: $('.anura-gallery-container').first().parent().anuraGallery({server: server, search: {custom: search_query}});
