Please describe.\n\nChart.js has a mix of expandable groups and individual items within its sidebar. I can't migrate the docs from Vuepress to Vitepress because Vitepress will not allow individual items within the sidebar\n\n### Describe the solution you'd like\n\nThe types are currently:\r\n```\r\n export type Sidebar = SidebarGroup[] | SidebarMulti\r\n\r\n export interface SidebarMulti {\r\n [path: string]: SidebarGroup[]\r\n }\r\n```\r\n\r\nIt would be nice to change them to:\r\n```\r\n export type Sidebar = Array\u003CSidebarGroup|SidebarItem> | SidebarMulti\r\n\r\n export interface SidebarMulti {\r\n [path: string]: Array\u003CSidebarGroup|SidebarItem>\r\n }\r\n```\n\n### Describe alternatives you've considered\n\nMake a group with just an individual item in it. It's kind of an annoying user experience though\n\n### Additional context\n\nThe work-in-progress branch is here: https://github.com/benmccann/Chart.js/tree/vitepress\n\n### Validations\n\n- [X] Follow our [Code of Conduct](https://vuejs.org/about/coc.html)\n- [X] Read the [docs](https://vitepress.vuejs.org).\n- [X] Read the [Contributing Guidelines](https://github.com/vuejs/vitepress/blob/main/.github/contributing.md).\n- [X] Check that there isn't already an issue that asks for the same feature to avoid creating a duplicate.",[2943,2944],{"name":2880,"color":2881},{"name":2866,"color":2867},1225,"Enable SidebarItem only menu in sidebar","2023-08-13T00:04:15Z","https://github.com/vuejs/vitepress/issues/1225",0.73447394,{"description":2951,"labels":2952,"number":2954,"owner":2869,"repository":2870,"state":2883,"title":2955,"updated_at":2956,"url":2957,"score":2958},"### Is your feature request related to a problem?
