Current behavior

Focus is not set on the first textbox or control on loading the form.

Focus should be set on the first textbox or component on loading the form. A way to set tabindex would be helpful.

Open any of the examples, focus is not set on first textbox.
What is the motivation / use case for changing the behavior?

I would like auto focus on the first control on the form

just pass true to the focus property:

    {
      key: 'text',
      type: 'input',
      focus: true,
      ...
    },

      focus: true,
      ...
    },

Hi @aitboudad can you point me to the code line where the focus is actually set on the element? I mean, how is the field.focus=true converted to the actual focus on the form element?
