DropDownTree Overview

The DropDownTree is an editor of hierarchical data, rendered in a tree-like structure, which provides multiple selection options and custom nodes.

The DropDownTree wrapper for Vue is a client-side wrapper for the Kendo UI DropDownTree widget.

Basic usage

The following example demonstrates how to initialize the DropDownTree.

Installation

To initialize the DropDownTree, either:

• Use the CDN service, or
• Use Webpack.

Initializing with Webpack

1. Install Kendo UI and add a theme.

   Copy Codenpm install --save @progress/kendo-ui
   npm install --save @progress/kendo-theme-default

2. Install the Kendo UI DropDownTree package for Vue.

   Copy Codenpm install --save @progress/kendo-dropdowntree-vue-wrapper

3. Import the Kendo UI packages to the App component. If you use the Kendo UI components more than once in your application, add all Kendo UI-related files to the main.js file. If you use the Kendo UI components once in your application, add the Kendo UI-related files the component where they will be referred.

   Copy Codeimport '@progress/kendo-ui' // This will import the entire Kendo UI library
   // As an alternative, you could import only the scripts that are used by a specific widget:
   // import '@progress/kendo-ui/js/kendo.dropdowntree' // Imports only the DropDownTree script and its dependencies
   
   import '@progress/kendo-theme-default/dist/all.css'
   
   import { DropDownTree, DropDownTreeInstaller } from '@progress/kendo-dropdowntree-vue-wrapper'
   
   Vue.use(DropDownTreeInstaller)
   
   new Vue({
       el: '#app',
       components: {
           DropDownTree
       }
   })
