anura-tree

<anura-tree adapter="some-adapter" root="1337" icon="tag"></anura-tree>

Basic navigation tree, featuring automatic (based on selection) and manual folding of sub-trees.

Attributes

adapter

required: yes, live: yes, default: -

The adapter that this tree should talk to.

root

required: yes, live: yes, default: -, alias: root-node

The root node of your navigation (ID or String).

<anura-tree root="123"></anura-tree>

Bynder doesn't support folder structures, so collections used are instead when providing root="collections"

value

required: no, live: once, default: -

Which node in the tree should be selected initially. Subsequent selections by the user are reflected in this attribute, but are write-only after the initial load. Note that the state parameter node will override the initial selection.

fallback

required: no, live: on-load, default: -

Value to use when nothing is selected. May be "root" to use the tree's root node. Note that configuring a sub-node of the root works, but results in an odd UX.

icon

required: no, live: yes, default: 'folder'

The icon that each node in the tree should display (see anura-icon). Pass false to hide these icons.

<anura-tree icon="archive"></anura-tree>

depth

required: no, live: no, default: -

To what depth the tree should load subnodes.

<anura-tree depth="3"></anura-tree>

deselectable

required: no, live: no, default: -

Whether to allow a user to deselect a previously selected node. Otherwise the user can only change the selection.

<anura-tree deselectable></anura-tree>

show-count

required: no, live: no, default: -

Whether to show a count of how many items are in this node (provided your adapter supports this).

hide-empty

required: no, live: no, default: -

Whether to hide nodes that have a count of 0 (provided your adapter supports this).

title

required: no, live: yes, default: name of root node

Set a custom title, rather than the name of the root node.

<anura-tree title="a fancy tree"></anura-tree>

state

required: no, live: no, default: true

Whether to update the URL to persist the currently selected node (for sharing the link). This will use the components id to differentiate itself from other components. If you don't provide an ID, a hash of the component will be used. Set it to false to not keep any state at all.

<anura-tree state="false"></anura-tree>

hide

required: no, live: no, default: []

Comma-separated list of node IDs that you wish to hide (does not render them at all). You should use the DAMs permission system to achieve this, but if for some reason you can't, this is an option.

<anura-tree hide="123,456,789"></anura-tree>

node-type

required: no, live: yes, default: -

Which node type you wish to load. Usually not necessary, as an ID should be unique - it depends on your DAM (may be required to show all root nodes on the first level).

<anura-tree node-type="105"></anura-tree>

category-lookup

required: no, live: no, default: -

Whether to offer a lookup functionality for categories/nodes/folders by name. This replaces the tree with a list of matching items. Availability depends on your DAM.

<anura-tree category-lookup></anura-tree>

marker

required: no, live: yes, default: +/-

Change the way that the list icon markers (open/closed) look, one of triangle ▹, full-triangle ▸ or none

<anura-tree marker="triangle"></anura-tree>

Events

change

regular change event

node-clicked

{detail: {id: node.id, name: node.name}}

Fired whenever the user has clicked on a node, regardless whether a selection or a deselection has occurred.

node-selected

{detail: {id: node.id, name: node.name}}

Fired whenever the user has selected a node. This will also update the selected attribute of the component.

node-deselected

{detail: {id: node.id, name: node.name}}

Fired whenever the user has deselected a node. This will also remove selected attribute from the component.

Slots

• header - the header slot will appear before the title and tree content.

• footer - he footer slot will appear at the very end, after the tree content.

Parts

<ul part="tree-root">
    <li part="node-li">
        <a part="node-link">
            <anura-icon part="node-icon"></anura-icon>
            <span part="node-name">Wheel</span>
            <span part="node-counter">42</span>
        </a>
        <ul part="node-ul"><!-- snip, repeats inside --></ul>
    </li>
    <li><!-- snip, etc. --></li>
</ul>

E.g. color all the icons in the tree:

anura-tree::part(node-icon) { color: green; }
