How to Create Hierarchical Tree with HTML Code in Vue Diagram?

HTML content can be added in the Vue Diagram through an HTML type node. The shape property of the node allows you to set the type of node, and to create an HTML node, it should be set as “HTML”.

Diagram provides support to create a Hierarchical tree layout, which is used to arrange nodes automatically based on a predefined layout logic.

Create Hierarchical tree layout in diagram

1. To generate a layout from DataSource, you have to define the business object and add the necessary data to the DataSource collection. During the layout generation, nodes and connectors can be generated automatically with the information provided through the data source, and those items will be added to NodeCollection and ConnectorCollection respectively.
2. To arrange the nodes in a hierarchical structure, specify the layout type as HierarchicalTree.

data: function () {
   return {
     width: '100%',
     height: '700px',
     snapSettings: { constraints: SnapConstraints.None },
     nodeTemplate: function () {
       return {
         template: createApp({}).component('nodeTemplate', NodeTemplate),
       };
     },
     created: function () {
       var diagramInstance =
         document.getElementById('diagram').ej2_instances[0];
       diagramInstance.dataSourceSettings = {
         id: 'Id',
         parentId: 'Manager',
         dataSource: new DataManager(localBindData),
       };
       //Configures automatic layout
       diagramInstance.layout = {
         type: 'HierarchicalTree',
       };
     },

     //Defines the default node and connector properties
     getNodeDefaults: (obj, diagram) => {
       return nodeDefaults(obj, diagram);
     },
     getConnectorDefaults: (connector, diagram) => {
       return connectorDefaults(connector, diagram);
     },
   };
 }, 

Create the Hierarchical layout with HTML Node

1. To create an HTML node, you should set the type of node shape to HTML.
2. To add HTML code, define the HTML code in the nodeTemplate.

function nodeDefaults(obj, diagram) {
 obj.shape ={type:'HTML'}
 obj.backgroundColor = '#6BA5D7'
 obj.width = 80;
 obj.height = 80;
 return obj;
} 

<template>
 <div
   :style="{
     background: data.color,
     height: '100%',
     width: '100%',
     position: 'absolute',
   }"
 >
   <div>
     <p class="myTitle">{{ data.data.Role }}</p>
   </div>
 </div>
</template>
