Okay I am certain this has asked before, so sorry for (probably) bringing up an "old question", but how would I add some text into a document without giving the user a field to fill in? I want to add something like:
Hello!

This is
__ page, where you can edit __

This is not as straightforward as it might seem, because you’re looking to use variables in there, for example. You could create a custom input component for this though, one that doesn’t actually show a field 🙂
Have a look at this thread for a general direction and code examples of how to achieve it. You probably won’t need things like the Link import, but the overall principle is the same.

Let me know if that helps.

It won't let me access posts prior to April 3rd 😕

That must have fallen off the 10k limit cliff just now - I could access it when posting half an hour ago. Sorry about that. I’ll find a way to dig this up for you in about an hour 🙂

Hi again Per after a long hour 😉
So what you could do is create a custom component for this (rough idea):

// myIntroTextComponent.js
import React from 'react'
import PropTypes from 'prop-types'
import FormField from 'part:@sanity/components/formfields/default'

export default class IntroText extends React.Component {
  static propTypes = {
    type: PropTypes.shape({
      title: PropTypes.string,
      options: PropTypes.shape({
        intro: PropTypes.string.isRequired
      }).isRequired
    }).isRequired
  }

  render() {
    const {type} = this.props
    const {intro} = type.options

    return (
      <FormField label={type.title}>
        {intro}
      </FormField>
    )
  }
}
And then include it in your schema as follows:

import MyIntroTextComponent from '../components/myIntroTextComponent'
...
    {
      name: 'hello',
      title: 'Hello!',
      type: 'string',
      inputComponent: MyIntroTextComponent,
      options: {
        intro: 'This is some page, where you can edit something'
      }
    }
...
You can make the above more flexible and add extra options, import a Link component (
import {Link} from 'part:@sanity/base/router'
), or whatever you need, but hopefully the above helps lay the foundation.
