Hello Durgpal,

I'm able to collapse the blocks of JavaScript code in my editor by clicking on / buttons on the left ruler:

The only thing I had to do in order to make those buttons to became available is to save the file (if it's not saved). This is a bug and we're going to get rid of this issue in future versions.

In case I've got your issue wrong, please clarify your situation by giving us more details, like version of Developer Studio, screenshots and etc.

Thanks in advance,

way where I can do that.
