Hello Jeff,
You can display any task property or even HTML elements instead of the standard task text.
Here is an example: http://snippet.dhtmlx.com/3c6566f37
If you want to modify the task text on the backend after loading the data, you need to update tasks. Here is another example: http://snippet.dhtmlx.com/d4a1c4d09
I really need the whole thing to be read-only.
When I ran the example code, it changed both the sidebar and the contents of the task. I want the sidebar to not change.
What I want is to have the task name on the left be different from the text in the schedule bar. The schedule component is going to contain some meta-data about the task.
