我想将 2 个下拉列表并排放在我拥有的搜索栏旁边，但我只能将它们放置在它下面。我希望有人能帮助我。下面是我的代码
<div>
<div class="input-group">
<div class="icon-addon">
<input type="text" id="search" class="form-control"
placeholder='Type to filter the table...'>
<label style="z-index: 22" for="search" class="fa fa-search" rel="tooltip"
title="search"></label>
</div>
</div>
</div>
</div>
<select class="form-control" style="width: 105px;">
<option>Festpreis</option>
<option>Stundenbasis</option>
</select>
下面是它的代码：
