Expanding/collapsing several branches not by id,

Hey I want to Expanding/collapsing several branches but not by their id property, but custom property instead.

Is this possible?

Thanks.

Hello Adir,
The open and close methods accept only the id parameter.
If you want to do something else, you need to implement a custom solution.

For changing how the task is displayed, you can modify its temporary property $open:

However, do you really need that? Maybe it is better to add a condition check to determine if the branch should be collapsed?
For example, you can try something like this:

if (task.property == 'collapse_me') gantt.close(task.id);

Got you, thank you for your answer Ramil.
