<form class="navbar-form navbar-left navbar-input-group" role="search" name="basicSearch" id="basicSearch">
<div class="form-group">
<div class="input-group" style="">
<input type="text" id="users" class="form-control" placeholder="Search Customer ...">
<span style="" class="input-group-btn">
<button class="btn btn-default" type="button">Go!</button>
</span>
</div>
</div>
</form>

Is there a way to revert the navbox input size back to its original default?
