How to render a form with 2 fields for each line?

Question

I'm looking for a way to render a form with 2 text-fields in to the same (for each) line. I would like to do this using hook functions, so I tried with this:

function mymodule_form_alter(&$form, &$form_state, $form_id) {
  if ($form_id == 'form_page_1') {
    $form['#type'] = 'table';
  }
}

But obviously it doesn't work. Do you have any idea?

Answer 1

Can you just add wrapper to each field with bootstrap classes to both form elements?

    $form['field_1_wrapper'] = array(
      '#type' => 'container',
      '#attributes' => array('class' => array('col-sm-6')),
    );

     $form['field_1_wrapper']['field_1'] = array(
      '#type' => 'textfield',
      '#title' => t('Field 1'),
    );

    $form['field_2_wrapper'] = array(
      '#type' => 'container',
      '#attributes' => array('class' => array('col-sm-6')),
    );

    $form['field_2_wrapper']['field_2'] = array(
        '#type' => 'textfield',
        '#title' => t('Field 2'),
    );
