Expand all Models at once

Content & configuration

Swagger-UI configuration options:

   SwaggerUI({
     spec,
     domNode: swaggerRef.current,
     defaultModelsExpandDepth: 10,
     defaultModelExpandDepth: 10,
     docExpansion: 'list',
     plugins: swaggerPlugins,
     showExtensions: true,
   });

Is your feature request related to a problem?

Users have to expand each schema under the "Model" section individually.

Describe the solution you'd like

Having an "Expand All" button to expand all schemas by default.

Describe alternatives you've considered

The defaultModelsExpandDepth seems to only work at the top level to expand the models, and doesn't seem to have any effect on expanding the individual models itself. The only significant change I see is when I set it to 0 the Models section is collapsed, and -1 hides it.

Start at the SwaggerUI configuration entry point and review how defaultModelsExpandDepth, defaultModelExpandDepth, and docExpansion affect the Models section. Trace the model rendering behavior to determine where an Expand All control or equivalent default behavior belongs. Done means users can expand all schemas together while the existing depth and visibility options continue to work.
