I have a custom form in Drupal.

When a user first sees this form, the only thing on the page is a select box, along with a few other elements they have to fill out.

When they make a selection from the select box, the #ajax callback regenerates the form, and adds about 50 results to the page.

By default, Drupal is scrolling down to the last result. This is a problem, because the users have to scroll back up to the elements near the top of the page to finish their work.

Is there a way to prevent Drupal from scrolling to the bottom of the newly-added form content?

Here is a snippet that shows how I'm setting up the form:

$form = array(
'#tree' => TRUE,
'#prefix' => '<div id="myform">',
'#suffix' => '</div>',

Here is a snippet from the select box that triggers returning the results.

$form['selectbox'] = array(
  '#type' => 'select',
  '#title' => t('Select box'),
  '#options' => $predefined_select_options,
  '#empty_option' => t('Select something!'),
  '#ajax' => array(
    'callback' => 'mymodule_form_ajax',
    'wrapper' => 'myform',
    'effect' => 'fade',

$form['other_stuff'] = array(
  '#type' => 'textfield',
  '#title' => t('Other stuff they need to fill out here'),

if (isset($form_state['values']['select box'])) {
  foreach ($lots_of_results as $result) {
    $form[$result] = array(
      '#type' = 'fieldset',
      '#title' = 'Lots of results in their own field sets',
  // It scrolls to the bottom of this huge list after it's rendered.

Here is the ajax handler for the select box.

function mymodule_form_ajax($form, $form_state) {
  return $form;

You could override the Drupal.ajax.prototype.success handler (/misc/ajax.js) in your theme to control behavior, maybe commenting out Drupal.unfreezeHeight(); and Drupal.freezeHeight(); could do the job? Just copy the whole function and manipulate it your own way.

 * Handler for the form redirection completion.
Drupal.ajax.prototype.success = function (response, status) {
  // Remove the progress element.
  if (this.progress.element) {
  if (this.progress.object) {


  for (var i in response) {
    if (response.hasOwnProperty(i) && response[i]['command'] && this.commands[response[i]['command']]) {
      this.commands[response[i]['command']](this, response[i], status);

  // Reattach behaviors, if they were detached in beforeSerialize(). The
  // attachBehaviors() called on the new content from processing the response
  // commands is not sufficient, because behaviors from the entire form need
  // to be reattached.
  if (this.form) {
    var settings = this.settings || Drupal.settings;
    Drupal.attachBehaviors(this.form, settings);


  // Remove any response-specific settings so they don't get used on the next
  // call by mistake.
  this.settings = null;

Another option would be to render the ajax form with ajax_commands where you could add custom js handlers to your callback.


Ran into this issue, where after ajax replace, it would auto scroll up to the top of the page.

 '#ajax' => [
    'callback' => 'mymodule_form_ajax',
    'wrapper' => 'myform',
    'disable-refocus' => true, // <-- The solution


  '#type' => 'submit',
  '#value' => $this->t('Submit'),
  '#ajax' => [
    'callback' => '::submitForm',
  '#attributes' => ['data-disable-refocus' => 'true'], // <-- The solution
