Examples

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

Simple


{
  type: 'string',
  name: 'title',
  label: 'Title'
}

Simple w/ List

Setting list: true will make the value an array

{
  type: 'string',
  name: 'title',
  label: 'Title',
  list: true
}

As a list w/ options

Setting list: true and providing options will make the value an array with a selection list

{
  type: 'string',
  name: 'title',
  label: 'Title',
  list: true,
    options: [
      {
        value: "movies",
        label: "Movies"
      }, {
        value: "music",
        label: "Music"
      }
    ]
}

Using the isBody property

When working with markdown, you can indicate that a given field should represent the markdown body

{
  type: 'string',
  name: 'body',
  label: 'Body',
  // Indicates this field should repesent the file's body
  isBody: true
}

Override the built-in component

By default, the text field is used for strings. To use a different core field plugin, specify it with the ui.component property

{
  label: "Description",
  name: "description",
  type: "string",
      ui: {
    component: "textarea"
  }
}

Providing a custom component

You can create your own components

{
  label: "Title",
  name: "title",
  type: "string",
      ui: {
    component: ({ input }) => {
      return (
        <div>
          <label htmlFor="title">Title: </label>
          <input {...input}></input>
        </div>
      );
    },
  },
}
