Transform control centered not in left

I’m animating a door by rotating but when I rotate the door all position changed and I noticed that my Transform control(or whatever it is called) is in the center of an object unlike in this image

this is what my control look like

What I want is to rotate the door while the left side of the door is still in the position. Please help

If you cant reset or move the mesh pivot you can add scenecomponent and set the door as its child. Move the door in the hierarchy that the sceneomponent is in the location where you like the pivot. Then rotate the scenecomponent as pivot and the children should follow.
