Drag and Drop functionality is not exposed currently through Oxygen (we will add it in the next version).
But it’s possible to use the underlying webdriver directly.
This will drop grey rectangle into red square. You’ll see “Dropped” written in one of the edit fields after the rectangle was dropped.
dragAndDrop command receives locator for the element you want to drop as first argument, and the locator of the element where to drop to as second argument.
Note that locators here are not Oxygen locators. If you want to find element by ID then prepend # to the id (like the first argument in the example bellow). XPath (like the second argument in the example below) is identical to how it’s used in Oxygen.
