I am dynamically placing objects correct on the screen in a gooey static_list, but the sec i move the mouse and on_input is executed the position is changing and everything in the list is not placed at the correct place anymore. What is making the Y cordinates to change? anyone have a idea? @britzl maybe? 
Gooey will automatically child the list items to the provided node and it will also automatically arrange the list items one after the other once when the list is created: https://github.com/britzl/gooey/blob/master/gooey/internal/list.lua#L141
Take a look at the example using the Kenney Blue theme. There’s both a static and a dynamic list in that screen: https://github.com/britzl/gooey/tree/master/example
