Configure field mapping

Hello!
Is there a configuration field mapping?
I want to change the start_date to the startDate.
How to realize it conveniently?

Hello Virgil,
There is no built-in way to do that. Gantt needs to have properties with certain names to correctly process tasks.
You can store the dates in custom properties with any names, but when you load the data in Gantt, you need to copy the values from them to the properties that Gantt expects to see.

Here is an example of how it might be implemented:
