Describe the bug

Here is what my project directory looks like

.
├── cmd/
│   ├── myapp/
│   │   ├── file1.go
│   │   └── file2.go
│   └── myanotherapp/
│       ├── file1.go
│       └── file2.go
└── pkg/
    └── mylibrary/
        ├── file1.go
        ├── file2.go
        ├── go.mod
        └── go.sum

Importing any external library in mylibrary module (and even myapp/myotherapp), causes intellisense suggestions to not show up. However, opening any of the folders individually (like opening only folder mylibrary or myapp), resolves the error.

Steps to reproduce the behavior:

1. Create a similar project directory structure as above
2. Try importing an external package (in my example, github.com/urfave/cli/v2).
3. You will observe intellisense suggestions not appearing.
4. Doing the same by opening only the folder myapp on vscode, causes the intellisense to work correctly.

@infixint943 thanks for the report. That's a known issue. golang/go#36899 describes the current limitation and the improvement plan. Currently the best workaround is to use Workspace Folders per module - for every go.mod, add the module root using "File" > "Add Folder to Workspace". (golang/go#32394)

@stamblerre Let's create a pinned issue on vscode-go side. It became the most common issues users face nowadays.

Good idea - done: #275.

Thanks @stamblerre

I will close this issue in favor of the pinned issue.
