**Do you mean the toolbar across the top of the window?** If you look around at the top edge of the EasyEDA window, just below the browser URL (web address) bar, you will find an horizontal thin blue strip. If you move the mouse over the strip, you will find that a tooltip of `Toggle toolbar` appears: ![enter image description here][1] Click on it and the top toolbar will reappear: ![enter image description here][2] Click on it again and the toolbar will hide again. There are similar, vertical strips down the left and right hand side. They can be hidden by clicking on the little white arrowheads in centre of the strip They can also be resized sideways by dragging the on the blue strip. :) [1]: /editor/20151217/5671ddca4481b.png [2]: /editor/20151217/5671dd9b8e929.png
