Bootstrap 3, how disable auto-added Glyphicon? I use Bootstrap (v3) with Drupal 8. When I create a button named "Search something", bootstrap adds automatically a "Search" Glyphicon. I do some web searches, but I don't find how "disable" (or hide?) the 'search'auto-added glyphicon of my button.

When I create a sample submit button from a Form Class custom module : 

public function buildForm(array $form, FormStateInterface $form_state) {
...
$form['submit'] = [
  '#type' =&gt; 'button',
  '#value' =&gt; 'Search something',
];    


If I go to the page where there is my form, the button have automatically a magnifying glass glyphicon : 



I want display my button without any glyphicon, how can I do that ? I must add a class to my button ? which ?

Thank you !
I haven't tried it for Drupal 8, but its works for drupal 7. It should work for drupal 8 as well.

In your bootstrap theme setting, under bootstrap setting there is tab of General setting. Inside that tab the are settings for different bootstrap components. You will see Buttons there. Just open that section and un-check Iconize Buttons option. That's it.

This will disable all the auto icons in buttons.
