用户是否可以从实用程序下拉列表(见下图)中选择会影响搜索文本字段的搜索选项?

或者是否可以将下拉列表和搜索文本字段合并在一起?

I think you will be able to do this leveraging input-groups. But the docs also mention:
Avoid using elements here as they cannot be fully styled in WebKit browsers.
HTML to integrate a <select> in the navbar:
<form class="navbar-form navbar-left select-search" role="search">
<div class="input-group">
<span class="input-group-addon">
<select class="form-control">
<option>1</option>
<option>2</option>
<option>3</option>
<option>4</option>
<option>5</option>
</select>
</span>
<input type="text" class="form-control">
</div>
<button type="submit" class="btn btn-default">Submit</button>
</form>
Then apply the following CSS:
.select-search .input-group-addon {
padding: 0;
border: 0;
}
.select-search .input-group .input-group-addon > select.form-control {
border-top-left-radius: 4px;
border-bottom-left-radius: 4px;
}

I found this works well in chrome, but in firefox the select arrow got some button like styling:

I'm not sure how to fix the style of the select arrow here. Style the select with -moz-appearance:none or -moz-appearance:menulist won't help. Possible related to: Clearing the background of a <select> element's pulldown button with CSS
