  materials is a core directory that consolidates 2 subdirectories: fixed-semi-materials and form-materials.
  At the main level, 'fixed-semi-materials' includes 1 contained folders: src.
  In nested path 'fixed-semi-materials / src', The 'src' container contains 2 folders for code organization.
  In nested path 'fixed-semi-materials / src / assets', Inside 'assets', you'll find it has nothing inside.
  At level 3, in directory path 'fixed-semi-materials / src / components', 'components' incorporates 7 subdirectories that organize the source code.
  In nested path 'fixed-semi-materials → src → components → adder', Inside 'adder', you'll find it holds no subdirectories at the moment.
  At level 4, in directory path 'fixed-semi-materials → src → components → branch-adder', The 'branch-adder' directory is currently empty.
  At level 4, in directory path 'fixed-semi-materials / src / components / collapse', 'collapse' stands empty.
  In nested path 'fixed-semi-materials → src → components → drag-highlight-adder', Inside 'drag-highlight-adder', you'll find it has yet to be populated.
  At level 4, in directory path 'fixed-semi-materials > src > components > drag-node', 'drag-node' is currently empty.
  In nested path 'fixed-semi-materials > src > components > dragging-adder', Inside 'dragging-adder', you'll find it has yet to be populated.
  In nested path 'fixed-semi-materials / src / components / nodes', The 'nodes' repository hasn't been filled with any content.
  Back to the top level.
  At the main level, 'form-materials' houses 2 subdirectory elements: bin, src.
  In nested path 'form-materials / bin', Inside 'bin', you'll find it has no content.
  In nested path 'form-materials / src', 'src' holds 1 subdirectories that organize the source code.
  Within directory hierarchy 'form-materials / src / components', The 'components' container encapsulates 3 folders for code organization.
  Within directory hierarchy 'form-materials → src → components → json-schema-editor', Inside 'json-schema-editor', you'll find it contains no subdirectories.
  At level 4, in directory path 'form-materials > src > components > type-selector', Inside 'type-selector', you'll find it has no folders inside.
  In nested path 'form-materials / src / components / variable-selector', Inside 'variable-selector', you'll find it has no folders inside.
  Back to the top level.
