Collapse html in Visual Studio 2012

I was having this issue too and it was driving me nuts. Turns out that, somehow, I turned off "Automatic outlining" which meant that I did see the plus/minus signs and the shortcut Ctrl + M + M didn't work either.

After I turned on Automatic Outlining in Edit > Outlining > Start Automatic Outlining everything went back to normal.

NOTE: On some ocassions, for this solution to work, you also need to close and reopen the document before clicking on Start Automatic Outlining. In fact, sometimes that option doesn't appear in the menu if you don't do so.

It's still there. The issue is that sometimes it takes a while for the parser to visually enable collapsing.

Try Ctrl + M + M and you'll see the effect

I prefer using Ctrl + M + H whenever I want to hide unwanted code irrespective of any tree hierarchy. This works great even if I want to hide my commented code.

You just need to select the code that you want to collaspe and hit Ctrl + M + H and its hidden now :)

When you open the font .cshtml, you will have go to EDIT->Outlining->Start Automatic Outlining
