Add an action
When you are in the GANTT view of a folder, you can add an action directly from this view.
To do this, simply click on the +, as below:
A window allowing you to set up your new action will open.
Validate the addition of your action by clicking on save. This will appear in the list of actions of this folder, in the left window.
Add a sub-action
To add a sub-action, click on the plus of one of the actions in the left window and then follow the same steps as for creating an action.
Your sub-action will appear under your action, as below.
If you do not see your sub-action in the list, click on the + to the left of your action to display it.
