Link & Unlink Tasks

Links are also known as dependencies. It means one task relies on one or more tasks to be performed before it can be done. For example, Task 1 must be completed before Task 2 can begin. In this case, Task 1 is called a Predecessor as it precedes tasks that depend on it. The following task, Task 2, is called a Successor as it succeeds or follows tasks on which it is dependent.

To build such a relationship, you have 2 options:

  1. Use Mouse Click
  2. Click on a task bar (The Predecessor), then hold the mouse and drag it to another task bar (The Successor) to build a relationship.

  3. Use the Link Buttons on the Home Tab
    • Select two or more tasks on the list of the Gantt chart.
    • Click the Link buttonlink button on the Home tab.
    • To unlink the sequence or relationship between tasks, click the Unlink button unlink button on the Home tab.

To check whether a task has Predecessors or Successors, you can:

  1. Go to the Right Side Panel, click Link iconlink icon to open Link panel.
  2. link panel
  3. Switch between Predecessors and Successors sheets to view, add or remove corresponding links.


  • Editing the duration of linked tasks will automatically adjust their position on the timeline of the Gantt chart.
  • Any task can be a predecessor for one or more successor tasks. Likewise, any task can be a successor to one or more predecessor tasks.
