Rendering single data from an array

Question

{{dump(states)}} this returns

FormView {#5921 ▼
  +vars: array:33 [▼
    "value" => []
    "attr" => []
    "form" => FormView {#5921}
    "id" => "States"
    "name" => "States"
    "full_name" => "States"
    "disabled" => false
    "compound" => false
    "method" => "POST"
    "action" => ""
    "preferred_choices" => []
    "choices" => array:41 [▶]
    ]
  +parent: FormView {#5618 ▶}
  +children: []
  -rendered: false
  -methodRendered: false
}

@Loek I am asking that how to render a value from array,like _states.vars.choices.option 35_ — A.JRJ, Aug 31 '18 at 12:38
The same way you render anything in Symfony? `return $this->render('my-template', ['variable' => $variable])`? — Loek, Aug 31 '18 at 12:39

You can access array members in twig with the . or [] syntax.

Therefore the 35th choice of your choice array can be rendered like this in twig:

{{ states.vars.choices[34] }}

For further information how to access array members in twig take a look at this article from knpuniversity
