Boostrap dropdown bar not working there, how to fix?

Question

Bootstrap

With a full extension, everything works fine, when you click on "information" a window drops out ( class="dropdown-content" changes to class="dropdown-content show" )
In the mobile version, the window does not drop out, but if you look at the page code, it will change in the PC version, how to make it so that when you click, this window does not drop out of the PC version, but on the mobile. devices?
Code for PC:

<div class="dropdown">
  <button onclick="myFunction()" class="dropbtn"><i class="fa fa-bars" aria-hidden="true"></i> Информация</button>
  <div id="myDropdown" class="dropdown-content">
 <a href="/o-nas">О нас</a>
<a href="/oplata">Оплата</a>
<a href="/dostavka">Доставка</a>

<a href="/faq">Часто задаваемые вопросы</a>
  </div>
</div>

Mobile code:

<div class="dropdown">
  <button onclick="myFunction()" class="dropbtn"><i class="fa fa-bars" aria-hidden="true"></i> <span class="hidden-xs">Меню</span></button>
  <div id="myDropdown" class="dropdown-content">
 <a href="/o-nas">О нас</a>
<a href="/oplata">Оплата</a>
