Prerequisites

System requirements for Syncfusion Vue UI components

Dependencies

Following is the list of dependencies to use the Gantt with all features:

|-- @syncfusion/ej2-gantt
    |-- @syncfusion/ej2-base
    |-- @syncfusion/ej2-buttons
    |-- @syncfusion/ej2-calendars
    |-- @syncfusion/ej2-data
    |-- @syncfusion/ej2-dropdowns
    |-- @syncfusion/ej2-grids
    |-- @syncfusion/ej2-inputs
    |-- @syncfusion/ej2-layouts
    |-- @syncfusion/ej2-lists
    |-- @syncfusion/ej2-navigations
    |-- @syncfusion/ej2-popups
    |-- @syncfusion/ej2-richtexteditor
    |-- @syncfusion/ej2-treegrid

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 gantt component as an example. Install the @syncfusion/ej2-vue-gantt package by running the following command:

npm install @syncfusion/ej2-vue-gantt --save

or

yarn add @syncfusion/ej2-vue-gantt

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.

In this article, the Material theme is applied using CSS styles, which are available in installed packages. The necessary Material CSS styles for the Gantt component and its dependents were imported into the <style> section of src/App.vue file.

~/src/App.vue

<style>
@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-lists/styles/material.css';
@import '../node_modules/@syncfusion/ej2-layouts/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-richtexteditor/styles/material.css';
@import '../node_modules/@syncfusion/ej2-treegrid/styles/material.css';
@import "../node_modules/@syncfusion/ej2-vue-gantt/styles/material.css";
</style>

Note: Use above CSS styles in <style> </style> tag for rendering all code snippets.

Add Syncfusion Vue component

Follow the below steps to add the Vue Gantt component:

1. First, import and register the Gantt component in the script section of the src/App.vue file.

~/src/App.vue

<script>
import { GanttComponent } from "@syncfusion/ej2-vue-gantt";

export default {
  components: {
    'ejs-gantt': GanttComponent
  }
}
</script>

2. In the template section, define the Gantt component.

~/src/App.vue

<template>
    <div id="app">
    <ejs-gantt></ejs-gantt>
  </div>
</template>

Module injection

The Gantt components was segregated into individual feature-wise modules. To use its feature, you need to inject its feature service in the AppModule.
Find the relevant feature modules and descriptions as follows:

• Edit : Inject this module to use the editing feature.
• Filter : Inject this module to use the filtering feature.
• Sort : Inject this module to use the sorting feature.
• Selection : Inject this module to use the selection feature.
• Toolbar : Inject this module to use the toolbar items.
• DayMarkers : Inject this module to highlight the days.

Now, import the above-mentioned modules from the Gantt package and inject them using providelike following code:

~/src/App.vue

<script>
import { GanttComponent , Edit, Filter, Sort } from "@syncfusion/ej2-vue-gantt";
export default {
  provide: {
    gantt: [ Edit, Filter, Sort ]
  }
};
</script>

Binding Gantt with data

Bind data with the Gantt component by using the dataSource property. It accepts an array of JavaScript object or the DataManager instance.

~/src/App.vue

<template>
     <div>
        <ejs-gantt ref='gantt' :dataSource="data"></ejs-gantt>
    </div>
</template>
<script>
import { GanttComponent } from "@syncfusion/ej2-vue-gantt";
export default {
  components: {
    'ejs-gantt': GanttComponent
  },
  data: function() {
      return{
            data: [
            {
                TaskID: 1,
                TaskName: 'Project Initiation',
                StartDate: new Date('04/02/2019'),
                EndDate: new Date('04/21/2019'),
                subtasks: [
                    {  TaskID: 2, TaskName: 'Identify Site location', StartDate: new Date('04/02/2019'), Duration: 4, Progress: 50 },
                    { TaskID: 3, TaskName: 'Perform Soil test', StartDate: new Date('04/02/2019'), Duration: 4, Progress: 50  },
                    { TaskID: 4, TaskName: 'Soil test approval', StartDate: new Date('04/02/2019'), Duration: 4, Progress: 50 },
                ]
            },
            {
                TaskID: 5,
                TaskName: 'Project Estimation',
                StartDate: new Date('04/02/2019'),
                EndDate: new Date('04/21/2019'),
                subtasks: [
                    { TaskID: 6, TaskName: 'Develop floor plan for estimation', StartDate: new Date('04/04/2019'), Duration: 3, Progress: 50 },
                    { TaskID: 7, TaskName: 'List materials', StartDate: new Date('04/04/2019'), Duration: 3, Progress: 50 },
                    { TaskID: 8, TaskName: 'Estimation approval', StartDate: new Date('04/04/2019'), Duration: 3, Progress: 50 }
                ]
            },
        ],
        };
  },
};
</script>

Mapping task fields

The data source fields that are required to render the tasks are mapped to the Gantt control using the taskFields property.

~/src/App.vue

<template>
     <div>
        <ejs-gantt ref='gantt' :dataSource="data" id="GanttContainer" :taskFields = "taskFields" :height = "height"></ejs-gantt>
    </div>
</template>
<script>
import { GanttComponent } from "@syncfusion/ej2-vue-gantt";

export default {
  components: {
    'ejs-gantt': GanttComponent
  },
  data: function() {
      return{
            data: [
            {
                TaskID: 1,
                TaskName: 'Project Initiation',
                StartDate: new Date('04/02/2019'),
                EndDate: new Date('04/21/2019'),
                subtasks: [
                    {  TaskID: 2, TaskName: 'Identify Site location', StartDate: new Date('04/02/2019'), Duration: 4, Progress: 50 },
                    { TaskID: 3, TaskName: 'Perform Soil test', StartDate: new Date('04/02/2019'), Duration: 4, Progress: 50  },
                    { TaskID: 4, TaskName: 'Soil test approval', StartDate: new Date('04/02/2019'), Duration: 4, Progress: 50 },
                ]
            },
            {
                TaskID: 5,
                TaskName: 'Project Estimation',
                StartDate: new Date('04/02/2019'),
                EndDate: new Date('04/21/2019'),
                subtasks: [
                    { TaskID: 6, TaskName: 'Develop floor plan for estimation', StartDate: new Date('04/04/2019'), Duration: 3, Progress: 50 },
                    { TaskID: 7, TaskName: 'List materials', StartDate: new Date('04/04/2019'), Duration: 3, Progress: 50 },
                    { TaskID: 8, TaskName: 'Estimation approval', StartDate: new Date('04/04/2019'), Duration: 3, Progress: 50 }
                ]
            },
        ],
            height: '450px',
            taskFields: {
                id: 'TaskID',
                name: 'TaskName',
                startDate: 'StartDate',
                endDate: 'EndDate',
                duration: 'Duration',
                progress: 'Progress',
                child: 'subtasks'
            },
        };
  },
};
</script>

<style>
@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-lists/styles/material.css';
@import '../node_modules/@syncfusion/ej2-layouts/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';
@import "../node_modules/@syncfusion/ej2-vue-gantt/styles/material.css";
</style>

Note : While creating a Syncfusion Vue components using Direct Scripts, camelCased property (dataSource) names need to specify in the kebab-cased (data-source) equivalents.

Defining timeline

The Gantt has an option to define timeline using timelineSettings property with various options. Using this property we can customize the Gantt timeline.

~/src/App.vue

<template>
     <div>
        <ejs-gantt id="GanttContainer" :dataSource="data" :taskFields = "taskFields" :height = "height" :timelineSettings="timelineSettings"></ejs-gantt>
    </div>
</template>
<script>
import { GanttComponent } from "@syncfusion/ej2-vue-gantt";

export default {
  components: {
    'ejs-gantt': GanttComponent
  },
  data: function() {
      return{
            data: [
            {
                TaskID: 1,
                TaskName: 'Project Initiation',
                StartDate: new Date('04/02/2019'),
                EndDate: new Date('04/21/2019'),
                subtasks: [
                    {  TaskID: 2, TaskName: 'Identify Site location', StartDate: new Date('04/02/2019'), Duration: 4, Progress: 50 },
                    { TaskID: 3, TaskName: 'Perform Soil test', StartDate: new Date('04/02/2019'), Duration: 4, Progress: 50  },
                    { TaskID: 4, TaskName: 'Soil test approval', StartDate: new Date('04/02/2019'), Duration: 4, Progress: 50 },
                ]
            },
            {
                TaskID: 5,
                TaskName: 'Project Estimation',
                StartDate: new Date('04/02/2019'),

                    { TaskID: 8, TaskName: 'Estimation approval', StartDate: new Date('04/04/2019'), Duration: 3, Progress: 50 }
                ]
            },
        ],
            height: '450px',
            taskFields: {

                    format: 'MMM dd, yyyy',
                    unit: 'Week',
                },
                bottomTier: {
                    unit: 'Day',
                },
            },
      };
  },

Enabling toolbar

The toolbar property is used to add the toolbar items like Add, Remove, Edit, Update, Delete, Expand All,Collapse All in Gantt.

To use toolbar, inject the Toolbar module in the provide section.

~/src/App.vue

<template>
     <div>
        <ejs-gantt ref='gantt' id="GanttContainer" :dataSource="data" :taskFields = "taskFields" :height = "height" :toolbar="toolbar" :editSettings= "editSettings"></ejs-gantt>
    </div>
</template>
<script>
import { GanttComponent, Edit, Selection, Toolbar, DayMarkers  } from "@syncfusion/ej2-vue-gantt";

export default {
  components: {
    'ejs-gantt': GanttComponent
  },
  data: function() {
      return{
            data: [
            {
                TaskID: 1,
                TaskName: 'Project Initiation',

Enabling editing

The editing feature enables you to edit the tasks in Gantt component. It can be enabled by using the editSettings.allowEditing and editSettings.allowTaskbarEditing properties.

To use Editing, inject the Edit module in the provide section.

The following editing options are available to update the tasks in Gantt:

• Cell
• Dialog
• Taskbar
• Connector line

Cell editing

Modify the task details through cell editing by setting the edit mode property as Auto. To enable edit support Edit module should be injected in Gantt. If Edit module is not injected, you cannot do any editing action in Gantt.

~/src/App.vue

<template>
     <div>
        <ejs-gantt ref='gantt' id="GanttContainer" :dataSource="data" :taskFields = "taskFields" :height = "height" :toolbar="toolbar" :columns = "columns" :editSettings= "editSettings"></ejs-gantt>
    </div>

Enabling predecessors or task relationships

Predecessor or task dependency in the Gantt component is used to depict the relationship between the tasks.

Start to Start (SS) : You cannot start a task until the dependent task starts.
Start to Finish (SF) : You cannot finish a task until the dependent task finishes.
Finish to Start (FS) : You cannot start a task until the dependent task completes.
Finish to Finish (FF) : You cannot finish a task until the dependent task completes.

You can show the relationship in tasks, by using the dependency property as shown in the following code example:

<template>
<div>
<ejs-gantt id="gantt" :dataSource="data" :taskFields = "taskFields" :height="height"></ejs-gantt>
</div>
</template>

<script>
import { GanttComponent } from '@syncfusion/ej2-vue-gantt';

export default {
  components: {
    'ejs-gantt': GanttComponent
