I need to use a functionality that I do not know if UiPath is ready to give.
The point is that I need to click on a column separator and drag the mouse to the right. I know the Click Down mode but from there I do not know how to order it to move. Is there such functionality? Is it possible to do it in another way? maybe by code?
This is not an orchestrator question, but I think I can help you with this one
What you do to drag and drop is to use two Click activities. But instead of doing a regular click, you choose the ClickType Property CLICK_DOWN for the first one and CLICK_UP for the second on. This way the mouse click doesn’t get released until the CLICK_UP is executed, effectively making this combination a drag and drop!
I reread the question and write a second answer:
You could use a Hover activity to find the area or the element where you want to drop after dragging.

I’ve dealt with this before and the best way to drag and drop items was to use two click activities,
the first one with CLICK_DOWN Property and the second one is just a regular click (CLICK_SINGLE),
once you well define selectors to click on, you will be good to go.
