[Bug] showSubtechniques in SVGConfig does not show the sub techniques in the SVG

[KustoKing]

Expected Behavior

Expanded sub techniques in SVG

Actual Behavior

SVG is not showing sub techniques, while the attack navigator does

Steps to Reproduce the Problem

1. create a json with:
   layout: "expandedSubtechniques": "all"
   techniques "showSubtechniques": True
   "selectSubtechniquesWithParent": True
2. Validate that the json contains:
   layout: "expandedSubtechniques": "all"
   techniques: "showSubtechniques": true
   "selectSubtechniquesWithParent": true
3. Validate that the json works in attack explorer
4. Import: from mitreattack.navlayers.exporters.to_svg import ToSvg, SVGConfig
5. svgconf =SVGConfig(width=118.9, height=84.1, unit="cm", showHeader=False, fontSize=12, showSubtechniques="all")
6. export with
   exporter = ToSvg(domain='enterprise', source='local', resource=resource_path, config=svgconf)
   exporter.to_svg(layerInit=layer, filepath="Coverage.svg")

Hi @KustoKing,

Thanks for opening a request! You are right. There is a bug in the code used to expand the subtechniques in the SVG. We do plan to address this issue. As a workaround, I suggest you follow the steps below -

1. Open the layer in ATT&CK navigator
2. Select expand sub-techniques in the navigator toolbar
3. Download the layer
4. Then you can create the SVG using the new layer file and the mitreattack-python library

Alternatively, if you want to strictly make use of the mitreattack-python library, ensure that ALL techniques have been included in the layer file with showSubtechniques: true.

Let us know if you encounter any issues.
