@mr-c I would like to work on this issue. Can you please direct me on how to start, and what all files to look at? I've done the installation.

Copying my response from gitter:

I would start with understanding what a subworkflow is, and how it is expressed in CWL. I suggest going through this training https://www.commonwl.org/rnaseq-training/ .

Subworkflows are introduced in lesson 5.

Example: https://view.commonwl.org/workflows/github.com/genome/analysis-workflows/blob/0b6e8fd8ead7644cf5398395b76af5cf4011686f/definitions/subworkflows/sequence_to_bqsr_nonhuman.cwl

The orange box named "adapter for sequence_align_and_tag" is a sub workflow. Today, if you double click that box then it opens separately.

The goal would be that the orange box expands to include the contents on this page.

A packed.cwl example:

https://view.commonwl.org/workflows/gitlab.com/m-unlock/cwl/blob/dev/cwl/workflows/packed/workflow_metagenomics_assembly.cwl

which retrieves this workflow:

https://gitlab.com/m-unlock/cwl/-/tree/dev/cwl/workflows/packed

This is a compact representation of a workflow with multiple subworkflows from https://gitlab.com/m-unlock/cwl/-/blob/dev/cwl/workflows/workflow_metagenomics_assembly.cwl in case you needed additional examples.
