Unlocking the potential of the Bootstrap search dropdown

Currently, I am utilizing the following code to create a searchable dropdown menu. I found helpful guidance in this forum post.

I am seeking advice on how to retrieve the value of the selected option. For example, if 'China' is chosen, I would like to assign the variable var country = 'CN'.

My attempts thus far have been unsuccessful as most methods return 'US'. This may be due to 'United States' being the first option in the dropdown list.

Country: 
  <select class="form-control selectpicker" id="select-country" data-live-search="true">
    <option disabled>Select a Country</option>
    <option data-tokens="United States" value="US">United States</option>
    <option data-tokens="United Kingdom" value="GB">United Kingdom</option>
    <option data-tokens="China" value="CN">China</option>
    <option data-tokens="Japan" value="JP">Japan</option>
  </select>
