Dragable gui?

how i can create a dragable gui?

When the UI is click, send a signal, then when that signal is dispatched and received, create states in which the ui is in like DOCKED and UNDOCKED. Then when signal is recieved, switch the state of the ui, make the x position of your ui the same as the mouse position via HudUpdate through some other function.

Note: You don't have to add the state DOCKED And UNDOCKED, just for versatility.

Or you can just look at how the stat is done.
