You can set the position of a side menu window using a single property. The available options are left, right, top, and bottom sides of the screen.
If you set the right or left position for the side menu widget, it will automatically adjust its height to the screen height. Similarly, if the side menu window appears from the top or bottom of the screen, it will adjust its width to the screen width. If needed, you can set the required width and height values manually.
