Hello,
You can vertically reorder tasks in the grid. To do that, you need to enable the order_branch config:
https://docs.dhtmlx.com/gantt/desktop__reordering_tasks.html

Here are examples:
https://docs.dhtmlx.com/gantt/samples/07_grid/14_branch_ordering_highlight.html

https://docs.dhtmlx.com/gantt/samples/07_grid/08_drag_between_levels.html

If you want to vertically reorder tasks in the timeline, Gantt doesn’t have that feature. The dev team will add it in the future, but I cannot give you any ETA.
So, if you want to have this functionality now, you need to implement a custom solution.

The following article shows the examples of the implementation:
https://docs.dhtmlx.com/gantt/desktop__how_to.html#howtoverticallyreordertasksinthetimeline

Also, if you want to receive the answers to your questions sooner, you can submit support requests via email. You can find the support email in the letter with the license.

So, what I need is that if someone selects an event from one split task and adds it to another split task, it should work correctly. Also, if someone has one event and adds it to some other split event task, it should work perfectly.

Hello,
The examples in the article above allow changing the task position from one split task to another. If you want to make it work as you want, you need to customize the code to fit your needs.
If you want us to implement a custom solution for you, you can contact the Sales team:
