How to create tags

I’m trying to create tags for my blog, just need to be a simple list but I’m running into the following issues where it’s not working can’t add more than one.

Typically, you create tags with the list widget.

Three examples:

- label: "Tags"
  name: "tags"
  widget: "list"
- label: "Tags"
  name: "tags"
  widget: "list"
  summary: '{{fields.name}}'
  field: {label: Name, name: name, widget: string}
- label: "Tags"
  name: "tags"
  widget: "list"
  summary: '{{fields.name}}'
  fields: 
    - {label: Name, name: name, widget: string}

Thanks, I got it working right after posting
