In case you were wondering how you get dojo code support in PHPStorm even if dojo is not in your project folder, here’s the solution:

Make code assist for dojo work if it is in an external directory.

1. Open Project Settings

2. Select Directories

3. Add the path to your dojo folder as a new Content Root.

4. Mark the directories dijit, dojo, dojox as a Resource Root

That’s it.
