SwaggerHierarchySupport

This is a small Nuget package that can be used to add support for hierarchical tags in SwaggerUI. It uses a plugin for SwaggerUI that is located at:

Hierarchical Tags

To use the plugin, you need to install the Nuget Package:

> > dotnet add package WilderMinds.SwaggerUIHierarchySupport

Once you've installed the package, you just need to add the support like this:

  app.UseSwaggerUI(opt =>
  {
    opt.AddHierarchySupport();
  });

To create the hierarchy, you'll want to use Tags with a colon (:) or pipe (|) as delimiters as seen here:

app.MapGet("/weatherforecast", () =>
{
  var forecast = Enumerable.Range(1, 5).Select(index =>
      new WeatherForecast
      (
          DateOnly.FromDateTime(DateTime.Now.AddDays(index)),
          Random.Shared.Next(-20, 55),
          summaries[Random.Shared.Next(summaries.Length)]
      ))
      .ToArray();
  return forecast;
})
.WithName("GetWeatherForecast")
.WithTags("Weather:Forcast") // Weather is the top level, and the Forcast is the sub-tag
.WithOpenApi();
