Yes,
Sliding form is possible.
I had created long back.
Methods of achieving this are,
1. Using the new containers and defining formulas with the form respectively to change its X value.
2. Formula based on your screen size to change X-value without using containers.
3. Use for Timer control to give a sliding animation. Where the X-value starts from A and moves to B in n seconds. (Note: won't recommend if your screen lags else its okay)
4. Use of a slider. This will move Form from A to B on your screen. (Effective if Timer is not required and animation is required).
Hope this helps.
