Simple Interactive Gantt Chart Creator

A simple, lightweight, interactive gantt chart where the users are able to add, edit, expand, collapse schedules on the client side.

How to use it:

To get started, insert the stylesheet frappe-gantt.css and JavaScript frappe-gantt.js into the html page.

<link rel="stylesheet" href="frappe-gantt.css">
<script src="frappe-gantt.js"></script>

Create an element to hold the gantt chart.

<div class="gantt-target"></div>

Create your own scheduled tasks in a JavaScript array as follows:

var tasks = [
    {
      start: '2018-10-01',
      end: '2018-10-08',
      name: 'Redesign website',
      id: "Task 0",
      progress: 91
    },
    {
      start: '2018-10-03',
      end: '2018-10-06',
      name: 'Write new content',
      id: "Task 1",
      progress: 55,
      dependencies: 'Task 0'
    },
    {
      start: '2018-10-04',
      end: '2018-10-08',
      name: 'Apply new styles',
      id: "Task 2",
      progress: 40,
      dependencies: 'Task 1'
    },
    {
      start: '2018-10-08',
      end: '2018-10-09',
      name: 'Review',
      id: "Task 3",
      progress: 20,
      dependencies: 'Task 2'
    },
    {
      start: '2018-10-08',
      end: '2018-10-10',
      name: 'Deploy',
      id: "Task 4",
      progress: 50,
      dependencies: 'Task 2'
    },
    {
      start: '2018-10-11',
      end: '2018-10-11',
      name: 'Go Live!',
      id: "Task 5",
      progress: 10,
      dependencies: 'Task 4',
      custom_class: 'bar-milestone'
    }
]
