Hello! I am an industrial engineering student and I am developing a small project with a Gantt chart. I am using an app developed by someone on Github and they were using the admin panel to insert the task data. I don't want my users to access the admin panel so I create forms to insert the data. The problem is that on the admin panel the app is using a class to use the treebeard function to order the tasks I also need to use it on the form but I don't know-how.
