9 Aug 202324 minutes to read
This article provides a step-by-step guide for setting up a Vue 2 project using Vue-CLI and integrating the Syncfusion Vue Treegrid component
To get start quickly with Vue tree grid, you can check on this video:
Prerequisites
System requirements for Syncfusion Vue UI components
Setting up the Vue 2 project
To generate a Vue 2 project using Vue-CLI, use the vue create command. Follow these steps to install Vue CLI and create a new project:
npm install -g @vue/cli
vue create quickstart
cd quickstart
npm run serve
or
yarn global add @vue/cli
vue create quickstart
cd quickstart
yarn run serve
When creating a new project, choose the option Default ([Vue 2] babel, eslint)
from the menu.
Once the quickstart
project is set up with default settings, proceed to add Syncfusion components to the project.
Add Syncfusion Vue packages
Syncfusion packages are available at npmjs.com. To use Vue components, install the required npm package.
This article uses the Vue Treegrid component as an example. Install the @syncfusion/ej2-vue-treegrid
package by running the following command:
npm install @syncfusion/ej2-vue-treegrid --save
or
yarn add @syncfusion/ej2-vue-treegrid
The –save will instruct NPM to include the TreeGrid package inside of the
dependencies
section of thepackage.json
.
Import Syncfusion CSS styles
You can import themes for the Syncfusion Vue component in various ways, such as using CSS or SASS styles from npm packages, CDN, CRG and Theme Studio. Refer to themes topic to know more about built-in themes and different ways to refer to themes in a Vue project.
The TreeGrid has different themes. They are:
- Material
- Fabric
- Bootstrap
- High Contrast
import components CSS as given below in <style>
section of the App.vue
file.
<style>
<!-- Material theme used for this sample -->
@import '../node_modules/@syncfusion/ej2-base/styles/material.css';
@import '../node_modules/@syncfusion/ej2-buttons/styles/material.css';
@import '../node_modules/@syncfusion/ej2-calendars/styles/material.css';
@import '../node_modules/@syncfusion/ej2-dropdowns/styles/material.css';
@import '../node_modules/@syncfusion/ej2-inputs/styles/material.css';
@import '../node_modules/@syncfusion/ej2-navigations/styles/material.css';
@import '../node_modules/@syncfusion/ej2-popups/styles/material.css';
@import '../node_modules/@syncfusion/ej2-splitbuttons/styles/material.css';
@import "../node_modules/@syncfusion/ej2-grids/styles/material.css";
@import "../node_modules/@syncfusion/ej2-treegrid/styles/material.css";
</style>
Add Syncfusion Vue component
Follow the below steps to add the Vue Treegrid component:
1. First, import and register the Treegrid component in the script
section of the src/App.vue file.
<script>
import { TreeGridComponent } from "@syncfusion/ej2-vue-treegrid";
export default {
components: {
'ejs-treegrid': TreeGridComponent
}
}
</script>
2. In the template
section, define the Treegrid component.
<template>
<div id="app">
<ejs-treegrid></ejs-treegrid>
</div>
</template>
Defining Row Data
Data for the TreeGrid component is bind by using the dataSource
property and value is defined in the Vue component.
It accepts either an array of JavaScript object or DataManager instance.
<template>
<div id="app">
<ejs-treegrid :dataSource="data" childMapping="subtasks" :treeColumnIndex="1"> </ejs-treegrid>
</div>
</template>
<script>
import { TreeGridComponent } from "@syncfusion/ej2-vue-treegrid";
let dataSource = [
{
taskID: 1,
taskName: 'Planning',
startDate: new Date('02/03/2017'),
endDate: new Date('02/07/2017'),
progress: 100,
duration: 5,
priority: 'Normal',
approved: false,
subtasks: [
{ taskID: 2, taskName: 'Plan timeline', startDate: new Date('02/03/2017'), endDate: new Date('02/07/2017'), duration: 5, progress: 100, priority: 'Normal', approved: false },
{ taskID: 3, taskName: 'Plan budget', startDate: new Date('02/03/2017'), endDate: new Date('02/07/2017'), duration: 5, progress: 100, approved: true },
{ taskID: 4, taskName: 'Allocate resources', startDate: new Date('02/03/2017'), endDate: new Date('02/07/2017'), duration: 5, progress: 100, priority: 'Critical', approved: false },
{ taskID: 5, taskName: 'Planning complete', startDate: new Date('02/07/2017'), endDate: new Date('02/07/2017'), duration: 0, progress: 0, priority: 'Low', approved: true }
]
},
{
taskID: 6,
taskName: 'Design',
startDate: new Date('02/10/2017'),
endDate: new Date('02/14/2017'),
duration: 3,
progress: 86,
priority: 'High',
approved: false,
subtasks: [
{ taskID: 7, taskName: 'Software Specification', startDate: new Date('02/10/2017'), endDate: new Date('02/12/2017'), duration: 3, progress: 60, priority: 'Normal', approved: false },
{ taskID: 8, taskName: 'Develop prototype', startDate: new Date('02/10/2017'), endDate: new Date('02/12/2017'), duration: 3, progress: 100, priority: 'Critical', approved: false },
{ taskID: 9, taskName: 'Get approval from customer', startDate: new Date('02/13/2017'), endDate: new Date('02/14/2017'), duration: 2, progress: 100, approved: true },
{ taskID: 10, taskName: 'Design Documentation', startDate: new Date('02/13/2017'), endDate: new Date('02/14/2017'), duration: 2, progress: 100, approved: true },
{ taskID: 11, taskName: 'Design complete', startDate: new Date('02/14/2017'), endDate: new Date('02/14/2017'), duration: 0, progress: 0, priority: 'Normal', approved: true }
]
}];
export default {
components: {
'ejs-treegrid': TreeGridComponent
}
data () {
return {
data: dataSource;
}
}
}
</script>
<style>
@import "../node_modules/@syncfusion/ej2-vue-treegrid/styles/material.css";
</style>
Defining Columns
The TreeGrid has an option to define the columns as an array. In these columns, the following properties are used to customize the columns.
- The
field
has been added to map with a property name in an array of JavaScript objects. - The
headerText
has been added to change the title of columns. - The
textAlign
has been used to change the alignment of columns. By default, columns will be left aligned. To change the columns to right align, define thetextAlign
toRight
. - Also, the another useful property,
format
has been used. Using this, you can format number and date values to standard or custom formats. Here it is defined for the conversion of date objects to formatted strings.
Tree Column is used to expand or collapse child rows is defined by using the treeColumnIndex
property.
<ejs-treegrid :dataSource='data' :treeColumnIndex='1' childMapping='subtasks'>
<e-columns>
<e-column field='taskID' headerText='Task ID' textAlign='Right' width=70></e-column>
<e-column field='taskName' headerText='Task Name' textAlign='Left' width=200></e-column>
<e-column field='startDate' headerText='Start Date' textAlign='Right' format='yMd' width=90></e-column>
<e-column field='duration' headerText='Duration' textAlign='Right' width=80></e-column>
</e-columns>
</ejs-treegrid>
In the above code example, we represent the hierarchical data binding in which chilMapping
property denotes the hierarchy relationship; whereas in self-referencing data binding idMapping
and parentIdMapping
denotes the hierarchy relationship.
Module injection
To create TreeGrid with additional features, inject the required modules. The following modules are used to extend TreeGrid’s basic functionality.
-
Page
- Inject this module to use paging feature. -
Sort
- Inject this module to use sorting feature. -
Filter
- Inject this module to use filtering feature. -
ExcelExport
- Inject this module to use Excel export feature. -
PdfExport
- Inject this module to use PDF export feature.
Register the required array of modules under the key treegrid
in the provide
section.
Additional feature modules are available here
Enable Paging
The paging feature enables users to view the TreeGrid record in a paged view. It can be enabled by setting the allowPaging
property to true. Also, need to inject the Page
module in the provide
section as follows. If the Page
module is not injected, the pager will not be rendered in the TreeGrid. The pager can be customized using the pageSettings
property.
In root-level paging mode, paging is based on the root-level rows only i.e., it ignores the child rows count and it can be enabled by using the pageSettings.pageSizeMode
property.

<ejs-treegrid :dataSource="data" :treeColumnIndex='1' childMapping='subtasks' :allowPaging="true" :pageSettings='pageSettings'>
<e-columns>
<e-column field='taskID' headerText='Task ID' textAlign='Right' width=90></e-column>
<e-column field='taskName' headerText='Task Name' textAlign='Left' width=180></e-column>
<e-column field='startDate' headerText='Start Date' textAlign='Right' format='yMd' width=90></e-column>
<e-column field='duration' headerText='Duration' textAlign='Right' width=80></e-column>

Enable Sorting
The sorting feature enables the user to order the records. It can be enabled by setting allowSorting
property to true. Also, need to inject the Sort
module in the provide
section as follow.
If we didn’t inject the Sort
module, then user not able to sort when click on headers. Sorting feature can be customized using sortSettings
property.

Enable Filtering
The filtering feature enables you to view the reduced amount of records based on the filter criteria. It can be enabled by setting the allowFiltering
property to true. Also, need to inject the Filter
module in the provide
section as follow. If Filter
module is not injected, filter bar will not be rendered in TreeGrid. Filtering feature can be customized using the filterSettings
property.
By default, filtered records are shown along with its parent records. This behavior can be changed by using the filterSettings-hierarchyMode
property.
