Visual Editing Requirements: Before a page can be setup with visual editing, it first needs to be using Tina's data-fetching.

In react, (or react based frameworks like Next.js) visual editing can be set up on a page with the useTina hook

Here is an example of setting up visual editing, on a NextJS-based site.

// ...
import { useTina } from 'tinacms/dist/react'

export default function Home(props) {
  // Pass our data through the "useTina" hook to make it editable
  const { data } = useTina({
    query: props.query,
    variables: props.variables,
    data: props.data,
  })

  // Note how our page title uses "data", and not the original "props.data".
  // This ensures that the content will be updated in edit-mode as the user types
  return <h1>{data.page.title}</h1>
}

export const getStaticProps = async () => {
  const pageResponse = await client.queries.page({ relativePath: 'home.mdx' })

  return {
    props: {
      data: pageResponse.data,
      query: pageResponse.query,
      variables: pageResponse.variables,
    },
  }
}

The useTina hook:

useTina is used to make a piece of Tina content contextually editable. It is code-split, so that in production, this hook will simply pass through its data value. In edit-mode, it registers an editable form in the sidebar, and contextually updates its value as the user types.

useTina takes in a parameter with a few keys:

• query and variables: These are the same values that you would use for the backend data-fetching.
• data: This is the production value that gets passed through to the response unchanged in production.

Note: Only queries for individual documents can be used with useTina

After a page is setup with the useTina hook, you can add a router to your collection so that you can access contextual-editing from the CMS.

Click to Edit (Experimental)

Tina's "click to edit" feature allows editors to select the element they want to edit on the page in order to see it in the sidebar.

Try the demo!

In order for this to work, Tina needs to know what document and field the element is associated with. Tina makes this easy with the tinaField helper function. Using this function, developers can add the appropriate metadata to the [data-tina-field] attribute.

import { useTina, tinaField } from 'tinacms/dist/react'

const Page = (props) => {
  const { data } = useTina(props)
  return (
    <div>
      <h1 data-tina-field={tinaField(data, 'title')}>{data.title}</h1>
    </div>
  )
}

Now, when you open the Tina sidebar you'll see editing overlays on any element that's been configured.
