I downloaded the source code of a demonstration and modified it. Then saved it as a CDF file. When I re-opened this file (in Mathematica or CDF Player), all of the code can be seen. How can I hide the code so that only the manipulation panel be shown? I want it to be seen just as the demonstrations on the website demonstration.wolfram.com.
I searched this site but found no solution to my problem. By the way, I use Mathematica 8.0.
If you do not want to display the code and any other cells other than the display, then select the cells you want to hide and do cell->cell properties ->open to flip it to close. Now all cells are closed other than the display Manipulate cells and any other you did not select to close.
