having trouble in the node window texture/object mode

Hi I’m having trouble in the node window in texture/object mode. If I click the X button the texture drop-down box and use node check box disappear. How do i bring them back? Once that menu is gone it seems like it gone from a file forever. Hopefully I’m just doing something silly. I’ve attached pictures to better explain
