How to hide x, y, z axis in "Material Graph node"

I’m a beginner of UE5. In a tutorial I see Material Graph node show as outfit, however it has this extend axis x, y, z in my side. So how could I hide it to have the same outfit as the first screenshot.

That’s the old way of displaying nodes.

If you change the constant to a parameter, it becomes more compact

I don’t think there’s an editor option for it.
