I'm having error with conditional rendering in Nextjs. If I have 1 component it works. With multiple components (block of code), it doesn't work

-> Its work:

const MyComponent = () => {
  return (
    <h1>Hello word</h1>

    { (isTrue) ? (
        <Text>Component 1</Text>
      ) : 'No component'
    }
  )
}

-> DON'T work :(

const MyComponent = () => {
  return (
    <h1>Hello word</h1>

    { (isTrue) ? (
        <Text>Component 1</Text>
        <Text>Component 2</Text>
      ) : 'No component'
    }
  )
}

It's not possible to render multiple elements / components at a time in React. You always have to wrap them in a single element or using a react fragment. For example, in your case should be:

const MyComponent = () => {
  return (
   <>
    <h1>Hello word</h1>

    { (isTrue) ? (
        <>
           <Text>Component 1</Text>
           <Text>Component 2</Text>
        </>
      ) : 'No component'
    }
   </>
  )
}

Yeah it might not work,
but you could try this by the use of fragments.

const MyComponent = () => {
return (
  <h1>Hello word</h1>

  { (isTrue) ? (
      <>
        <Text>Component 1</Text>
        <Text>Component 2</Text>
      </>
      ) : 'No component'
    }
  )
}
