Install the module Allowed Formats and configure the field to allow only one text format. Then the text format selector dropdown will no longer be displayed.

- I too prefer the D7 way but the D8 makes more sense from security POV.user21641– user216412017-06-22 10:51:05 +00:00Commented Jun 22, 2017 at 10:51

Adapted from the Allowed Formats code:
use Drupal\Core\Form\FormStateInterface; /** * Implements hook_field_widget_form_alter(). */ function mymodule_field_widget_form_alter(&$element, FormStateInterface $form_state, $context) { // Maps field names to an array containing a single format. $map = [ 'field_myfield' => ['myformat'], ]; $field_name = $context['items']->getFieldDefinition()->getName(); if (array_key_exists($field_name, $map)) { $element['#allowed_formats'] = $map[$field_name]; $element['#after_build'][] = '_remove_text_format_box'; } } /** * #after_build callback. */ function _remove_text_format_box($form_element, FormStateInterface $form_state) { // Remove help, guidelines and wrapper. unset($form_element['format']['help']); unset($form_element['format']['guidelines']); unset($form_element['format']['#type']); unset($form_element['format']['#theme_wrappers']); return $form_element; } 
If you use the #allowed_formats value and limit it to just 1 value; then the selector will disappear. This is code to add your own custom field; but I assume you can do a form alter to set these for an existing (UI placed) field.
$form['message_text'] = [ '#type' => 'text_format', '#format' => 'simple', '#allowed_formats' => ['simple'], '#title' => $this->t('Message Text:'), '#description' => $this->t('Some help text here.'), ];
