//...| Name | Required | Type/Value | Default | Description |
|---|---|---|---|---|
| data | no | Object |
null | Data representing tree structure, children nodes are represented by children property |
| duration | no | Number |
750 | Animation duration in milliseconds |
| layoutType | no | 'circular' 'vertical' or 'horizontal' | 'horizontal' | Circular, vertical or horizontal layout |
| leafTextMargin | no | Number |
6 | margin in pixel for leaf node text |
| linkLayout | no | 'bezier' or 'orthogonal' | bezier' | Define the link layout |
| identifier | no | Function |
() => i++ | Function that receives a data and returns its identity that can be a number or a string, useful when dynamically updating the tree |
| marginX | no | Number |
20 | margin for X axis in pixel |
| marginY | no | Number |
20 | margin for Y axis in pixel |
| maxZoom | no | Number |
0.8 | minimal zoom value |
| minZoom | no | Number |
9 | maximum zoom value |
| nodeText | no | String |
'name' | name of the property of the node to be used as a display name |
| nodeTextDisplay | no | 'all' 'leaves' or 'extremities' | 'all' | Determine wether all node texts are displayed or only leaf nodes or leaves and root node respectively. |

3 | node circle radius in pixel |
| selected | no | Object |
null |
The selected node -on which a selected class is applied-. It can be bound using a v-model directive. By default, click on text to select a node but this behavior can be customized using the behavior slot. |
| strokeWidth | no | Number |
1.5 | The path stroke-width in pixel. |
| type | no | 'tree' or 'cluster' | 'tree' | kind of layout: tree or cluster |
| zoomable | no | Boolean |
false | If true tree can be zoomed in using mouse wheel and drag-and-drop |
Use this slot to customize the rendering of individual node.
Note that the mark-up will be rendered inside a svg element, so only svg elements are allowed here
Slot-scope:
| Name | Type | Description |
|---|---|---|
| actions | Object |
Value: {collapse, collapseAll, expand, expandAll, setSelected, show, toggleExpandCollapse} where each property is a component method (see below for detailed description) |
| data | Object |
node data as provided by the data props |
| isRetracted | Bool |
true if the node has hidden children -retracted state- |
| isSelected | Bool |
true if the node is selected |
| node | D3.js node | D3.js node to be displayed |
| radius | Number |
tree radius props value |
Example:
<template #node="{data, node: {depth}, radius, isRetracted}">
<template v-if="data.children && data.children.length">
<path :fill="isRetracted? 'red' : 'blue'" d="M190.5..">
<title>{{data.text}} {{depth}}</title>
</path>
</template>
<template v-else>
<circle r="6" :stroke="blue? 'blue' : 'yellow'">
<title>{{data.text}} {{depth}}</title>
</circle>
</template>
</template>Use this slot to create a pop-up, tooltip or context menu for nodes. The position of the pop-up relative to its target is defined by the popUpPlacement prop.
By default, pop-up will open when clicking on node text. This behavior can be overridden using behavioral slot. For example by using the PopUpOnTextHover component provides opening of pop-up when hovering the node test. See below for example.
Slot-scope:
| Name | Type | Description |
|---|---|---|
| data | Object |
node data as provided by the data props |
| close | Function |
function to close the pop-up |
| node | D3.js node | D3.js node to be displayed |
Example:
<template #popUp="{data,node}">
<div class="btn-group-vertical">
<button @click="addFor(data)">
<i class="fa fa-plus" aria-hidden="true"></i>
</button>
<button @click="remove(data, node)">
<i class="fa fa-trash" aria-hidden="true"></i>
</button>
</div>
</template>Behavior slots provide an elegant way to customize the tree behavior by receiving as slot-scope both node information (including clicked node, hovered node, ...) and actions to alter the graph accordingly.
The concept of this slot is to react to changes in node information by calling an action
By design this slot is renderless.
For more about this pattern, you can check here.
Slot-scope:
| Name | Type | Description |
|---|---|---|
| on | Function |
Value: $on method of the tree component, exposing all events |
| actions | Object |
Value: {collapse, collapseAll, expand, expandAll, setSelected, show, toggleExpandCollapse} where each property is a component method (see below for detailed description) |
By default tree component use standardBehavior as component which provides toggle retract on node click and select the node on clicking on its text.
Example:
<tree>
<template #behavior="{on, actions}">
<CollapseOnClick v-bind="{on, actions}"/>
</template>
</tree>With CollapseOnClick component:
export default {
props: ['on', 'actions'],
render: () => null,
created () {
const {on, actions: {toggleExpandCollapse}} = this;
on('clickedNode', ({element}) => {
toggleExpandCollapse(element);
})
}
}To display pop-up on hover, use the built-in popUpOnHoverText:
<tree>
<template #behavior="{on, actions}">
<popUpOnHoverText v-bind="{on, actions}"/>
</template>
</tree>import {tree, popUpOnHoverText} from 'vued3tree'
export default {
components: {
tree,
popUpOnHoverText
},

a promise which resolve when animation is over | Retract or collapse the given node depending on its current state. |
This component is responsive and will adjust to resizing. In order for this to work properly, you must define for this component or its parent wether:
- a height or a max-height
- or a width or a max-width.
Failing to do so may result in a component whose size that will keep increasing.
