Can anyone help me understand why there is extra padding appearing under the drop-down select list in my panel header?
<div class="panel panel-default">
<div class="panel-heading clearfix">
<h3 class="panel-title pull-left">Status Connection History</h3>
<div class="form-group pull-right">
<select class="form-control" id="statusHistoryDropdown">
<option>Past Hour</option> <!-- increments of 5 minutes -->
<option>Past 12 Hours</option> <!-- increments of 1 hour -->
<option>Past 3 Days</option> <!-- increments of 6 hours -->
<option>Past 12 days</option> <!-- increments of 1 day -->
<option>Past Month</option> <!-- increments of 2 days -->
</select>
</div>
