Hello,
The “open” state is saved in the $open property:
https://docs.dhtmlx.com/gantt/desktop__task_properties.html#:~:text=the%20first%20task.-,%24open,-boolean
If you want to see the tasks opened or closed after you reload the page, you need to save the “open” state in the open property:
https://docs.dhtmlx.com/gantt/desktop__task_properties.html#:~:text=Specifies%20whether%20the%20task%20branch%20will%20be%20opened%20initially
By default, all tasks are loaded in the collapsed state:

But when there is the open:true property, Gantt expands the task:
The tasks can be opened if you enable the open_tree_initially config:
https://docs.dhtmlx.com/gantt/api__gantt_open_tree_initially_config.html
Here is an example:

But the open property has a higher priority over that config:
