Today a user complained that his children tasks were appearing on a gantt export despite the parent task being collapsed. After researching this, I found that this is by design. The documentation states that:
"Subtasks are included in the exported PDF even if the parent task is collapsed and the subtasks are not visible. To include only parent tasks, select the parent tasks you want to include and leave any subtasks unselected."
Unfortunately, due to this design, if a user has a lot of parent tasks, each with more than 10 subtasks below it, then the user would have to uncheckmark a lot of tasks just to get the view they need. This much manual maintenance can easily lead to mistakes and rework.
Additionally, while I understand that a filter can be created so that only parent tasks are displayed, there are cases where a user would want to leave some children tasks on the export.
