Template in Vue Treeview component
11 Jun 202410 minutes to read
The TreeView component allows you to customize the look of TreeView nodes by using the nodeTemplate
property. This property accepts either template string or HTML element ID.
In the following sample, employee information such as employee photo, name, and designation have been included using the nodeTemplate property.
<template>
<div id="app">
<div class="control_wrapper">
<ejs-treeview id='treeview' :fields="fields" cssClass='custom' :nodeTemplate='Template'></ejs-treeview>
</div>
</div>
</template>
<script setup>
import { TreeViewComponent as EjsTreeview } from "@syncfusion/ej2-vue-navigations";
import { createApp } from "vue";
var demoVue = createApp().component("demo", {
template: "<div><img class='eimage' :src='data.eimg' alt='employee'/><div class='ename'></div><div class='ejob'></div></div>",
data() {
return {
data: {}
};
}
});
var dataSource = [
{ id: 1, name: 'Steven Buchanan', eimg: 'https://ej2.syncfusion.com/demos/src/treeview/images/employees/10.png', job: 'CEO', hasChild: true, expanded: true },
