Pages by Tag 
You can use the OASpec component to render all operations that have a specific tag.
Creating tags pages 
To create tags pages, create a directory named tags in the docs directory. Inside the tags directory, create a file named [tag].md and a file named [tag].paths.js.
/docs
├── /tags
│   ├── [tag].md
│   └── [tag].paths.jsPaths Loader File 
Using the Paths Loader File feature of VitePress, you can use the [tag].paths.js file to generate the pages for each tag.
ts
import { usePaths } from 'vitepress-openapi'
import spec from '../public/openapi.json' assert { type: 'json' }
export default {
    paths() {
        return usePaths({ spec })
            .getTags()
            .map(({ name }) => {
                return {
                    params: {
                        tag: name,
                        pageTitle: `${name} - vitepress-openapi`,
                    },
                }
            })
    },
}Markdown File 
In the [tag].md file, you can use the OASpec component to render the operations that have the tag.
If you have configured the OpenAPI Specification using the useOpenapi composable in your .vitepress/theme/index.[js,ts] file, you can just pass the tag prop to the OASpec component, and it will automatically fetch the spec from the global context.
