How to indicate that a task has sub-tasks?

[Lisa6]

In Projects, there is a Project Tasks related list. That related list shows Top level tasks associated with that project.  Here's an example:

In this example, I created two sub-tasks underneath that parent task.  There is no indicator anywhere here that would suggest to the user that this task has child tasks, and this screen doesn't display subs in a collapse/expand list view.  

How do I provide a visual indicator to my users that there are sub tasks?  Is there a "Number of Children" type of field somewhere?  Or a way to have this list view display in a hierarchical collapse/expand list view?

Hi,

You can show this by enabling the hierarchical lists . Go to list control by right clicking on project task header and enable it.

Once you enable, you could see all sub tasks of project tasks within the Parent project itself.

You can add the Project task as an embedded list from the form layout, which will be easily visible to the users.

Other option is to write a onDisplay business rule to query Child project task and then display using gs.addInfoMessage() to display the number active task on this project

Ignore this response. I didn't read your question properly. Alikutty's answer should help
