Icon flags with value in dropdown menu

I have bootstrap dropdown menu with options to select. I want to add country flag near text on left side. And I did it, but the problem is when i select the option in dropdown and submit it, the flag is sent via php/html too. I dont know how to place it here to do not submit the flag with <li> and to have flag on the left side.

HTML:

<a class="btn btn-primary btn-select">
  <span class="btn-select-arrow glyphicon glyphicon-chevron-down"></span>
  <input class="btn-select-input" id="select_league" name="league" type="hidden">
  <span class="btn-select-value">All leagues</span>
  <ul style="display: none;">
    <li class=""><span class="flag-icon flag-icon-br"></span>Brazil</li>
    <li class=""><span class="flag-icon flag-icon-br"></span>Brazil</li>
    <li class=""><span class="flag-icon flag-icon-br"></span>Brazil</li>
    <li class=""><span class="flag-icon flag-icon-br"></span>Brazil</li>
    <li class=""><span class="flag-icon flag-icon-br"></span>Brazil</li>
    <li class=""><span class="flag-icon flag-icon-br"></span>Brazil</li>
    <li class=""><span class="flag-icon flag-icon-br"></span>Brazil</li>
    <li class=""><span class="flag-icon flag-icon-br"></span>Brazil</li>
    <li class=""><span class="flag-icon flag-icon-br"></span>Brazil</li>
  </ul>            
</a>
