Examples

Tina will generate the appropriate component depending on the configuration provided.

A basic object configuration

{
  label: "Testimonial",
  name: "testimonial",
  type: "object",
  fields: [
      {
        label: "Author",
        name: "author",
        type: "string"
      },
      {
        label: "Role",
        name: "role",
        type: "string"
      },
      {
        label: "Quote",
        name: "quote",
        type: "string",
        ui: {
          component: "textarea"
        }
      }
        ]
}

As a list with default values

{
  label: "Testimonials",
  name: "testimonials",
  type: "object",
        list: true,
          ui: {
    itemProps: (item) => {
      return { label: `${item?.author}  ( ${item?.role} ) ` }
    },
      defaultItem: {
      author: "Judith Black",
        role: "CEO",
          quote: "Lorem ipsum dol..."
    }
  },
  fields: [
    {
      name: "author",
      // ...
    },
    {
      name: "role",
      // ...
    },
    {
      name: "quote",
      // ...
    }
  ]
}

Using list object as a wrapper for other types

Number, boolean, datetime and rich-text field types can be used in this way to add list options to the TinaCMS editor.

Reference field types can be used in this way to create a list of references.

{
  label: "Author List",
  name: "authorList",
  type: "object",
  list: true,      
  fields: [
    {
      label: 'Author',
      name: 'author',
      type: 'reference',
      collections: ['author'],
    },
  ]
}

Using templates instead of fields

{
  label: "Page Blocks",
  name: "pageBlocks",
  type: "object",
  list: true,
  templates: [
    {
      label: "CTA",
      name: "cta",
      fields: [...]
    },
    {
      label: "Testimonial",
      name: "testimonial",
      fields: [...]
    }
  ]
}
