Firstly, please give appropriate titles to your post - not just "Hello I need an answer".
This does not help anyone searching the forums.
I have amended your title.
Now, morphs can not be exploded in 3D - that is why the command is not available.
You can do it in 2D, but you will just get lines and polylines.
It appears that your suspend groups is not active.
Turn this on and you may be able to select separate parts of your morph.
If it is still one morph, then you will have to use the split command to break it up.
