导航栏

创建具有下拉菜单的主站导航导航栏。

Navbar 组件使用相同的选项初始化所有下拉菜单,因此不需要单独初始化。导航栏内的所有下拉菜单都是目标感知的。这意味着只要鼠标指针移动到下拉菜单上,下拉菜单就会保持打开状态。额外的延迟确保即使鼠标指针短暂地移动到另一个方向,下拉菜单也会保持打开状态。在悬停模式下,如果悬停在另一个菜单项上,下拉菜单会立即关闭。

用法

Navbar 组件由一个导航栏容器、导航栏本身和一个或多个导航组成。

元素 描述
uk-navbar 将此属性添加到 <nav> 元素以定义 Navbar 组件。
.uk-navbar-container 将此类添加到同一个 <nav> 元素或父元素以添加导航栏背景样式。
.uk-navbar-left
.uk-navbar-center
.uk-navbar-right
将这些类中的一个添加到 <div> 元素以对齐导航。
.uk-navbar-nav 将此类添加到 <ul> 元素以创建导航。在列表中使用 <a> 元素作为菜单项。
.uk-parent 添加此类以指示父菜单项。
.uk-active 添加此类以指示活动菜单项。
<nav class="uk-navbar-container" uk-navbar>
    <div class="uk-navbar-left">
        <ul class="uk-navbar-nav">
            <li class="uk-active"><a href=""></a></li>
            <li class="uk-parent"><a href=""></a></li>
            <li><a href=""></a></li>
        </ul>
    </div>
</nav>
  • <nav class="uk-navbar-container" uk-navbar>
        <div class="uk-navbar-left">
    
            <ul class="uk-navbar-nav">
                <li class="uk-active"><a href="#">Active</a></li>
                <li>
                    <a href="#">Parent</a>
                    <div class="uk-navbar-dropdown">
                        <ul class="uk-nav uk-navbar-dropdown-nav">
                            <li class="uk-active"><a href="#">Active</a></li>
                            <li><a href="#">Item</a></li>
                            <li><a href="#">Item</a></li>
                        </ul>
                    </div>
                </li>
                <li><a href="#">Item</a></li>
            </ul>
    
        </div>
    </nav>

导航栏和导航栏容器都没有水平填充。若要设置与页面其余部分相同的水平填充,请使用 容器组件

<nav class="uk-navbar-container">
    <div class="uk-container">
        <div uk-navbar>…</div>
    </div>
</nav>
  • <nav class="uk-navbar-container">
        <div class="uk-container">
            <div uk-navbar>
    
                <div class="uk-navbar-left">
    
                    <ul class="uk-navbar-nav">
                        <li class="uk-active"><a href="#">Active</a></li>
                        <li>
                            <a href="#">Parent</a>
                            <div class="uk-navbar-dropdown">
                                <ul class="uk-nav uk-navbar-dropdown-nav">
                                    <li class="uk-active"><a href="#">Active</a></li>
                                    <li><a href="#">Item</a></li>
                                    <li><a href="#">Item</a></li>
                                </ul>
                            </div>
                        </li>
                        <li><a href="#">Item</a></li>
                    </ul>
    
                </div>
    
            </div>
        </div>
    </nav>

多个导航

您可以在一个导航栏容器中放置多个导航。这样,您可以在同一个导航栏中拥有左对齐、居中和右对齐的导航。

<nav class="uk-navbar-container" uk-navbar>
    <div class="uk-navbar-left">…</div>
    <div class="uk-navbar-center">…</div>
    <div class="uk-navbar-right">…</div>
</nav>
  • <nav class="uk-navbar-container">
        <div class="uk-container">
            <div uk-navbar>
    
                <div class="uk-navbar-left">
    
                    <ul class="uk-navbar-nav">
                        <li class="uk-active"><a href="#">Active</a></li>
                        <li>
                            <a href="#">Parent</a>
                            <div class="uk-navbar-dropdown">
                                <ul class="uk-nav uk-navbar-dropdown-nav">
                                    <li class="uk-active"><a href="#">Active</a></li>
                                    <li><a href="#">Item</a></li>
                                    <li><a href="#">Item</a></li>
                                </ul>
                            </div>
                        </li>
                        <li><a href="#">Item</a></li>
                    </ul>
    
                </div>
    
                <div class="uk-navbar-right">
    
                    <ul class="uk-navbar-nav">
                        <li class="uk-active"><a href="#">Active</a></li>
                        <li>
                            <a href="#">Parent</a>
                            <div class="uk-navbar-dropdown">
                                <ul class="uk-nav uk-navbar-dropdown-nav">
                                    <li class="uk-active"><a href="#">Active</a></li>
                                    <li><a href="#">Item</a></li>
                                    <li><a href="#">Item</a></li>
                                </ul>
                            </div>
                        </li>
                        <li><a href="#">Item</a></li>
                    </ul>
    
                </div>
    
            </div>
        </div>
    </nav>

透明修饰符

在网站的英雄区使用图像或彩色背景时,您可能希望将导航栏设置为透明。只需在与 .uk-navbar-container 类相同的元素上添加 .uk-navbar-transparent 类即可。如有必要,请添加 反转组件 中的 .uk-light.uk-dark 类以调整导航栏颜色。

<nav class="uk-navbar-container uk-navbar-transparent" uk-navbar></nav>
  • <div class="uk-position-relative">
        <img src="images/light.jpg" width="1800" height="1200" alt="">
        <div class="uk-position-top">
            <nav class="uk-navbar-container uk-navbar-transparent">
                <div class="uk-container">
                    <div uk-navbar>
    
                        <div class="uk-navbar-left">
                            <ul class="uk-navbar-nav">
                                <li class="uk-active"><a href="#">Active</a></li>
                                <li><a href="#">Item</a></li>
                                <li>
                                    <a href="#">Parent</a>
                                    <div class="uk-navbar-dropdown">
                                        <ul class="uk-nav uk-navbar-dropdown-nav">
                                            <li class="uk-active"><a href="#">Active</a></li>
                                            <li><a href="#">Item</a></li>
                                            <li class="uk-nav-header">Header</li>
                                            <li><a href="#">Item</a></li>
                                            <li><a href="#">Item</a></li>
                                            <li class="uk-nav-divider"></li>
                                            <li><a href="#">Item</a></li>
                                        </ul>
                                    </div>
                                </li>
                            </ul>
                        </div>
    
                    </div>
                </div>
            </nav>
        </div>
    </div>

副标题

要定义副标题,请在项目 <a> 元素内创建一个 <div> 元素。将 .uk-navbar-subtitle 类添加到另一个 <div> 元素。

<li>
    <a href="">
        <div><div class="uk-navbar-subtitle"></div>
        </div>
    </a>
</li>
  • <nav class="uk-navbar-container">
        <div class="uk-container">
            <div uk-navbar>
                    
                <div class="uk-navbar-left">
    
                    <ul class="uk-navbar-nav">
                        <li class="uk-active">
                            <a href="#">
                                <div>
                                    Active
                                    <div class="uk-navbar-subtitle">Subtitle</div>
                                </div>
                            </a>
                        </li>
                        <li>
                            <a href="#">
                                <div>
                                    Parent
                                    <div class="uk-navbar-subtitle">Subtitle</div>
                                </div>
                            </a>
                            <div class="uk-navbar-dropdown">
                                <ul class="uk-nav uk-navbar-dropdown-nav">
                                    <li class="uk-active"><a href="#">Active</a></li>
                                    <li><a href="#">Item</a></li>
                                    <li><a href="#">Item</a></li>
                                </ul>
                            </div>
                        </li>
                        <li>
                            <a href="#">
                                <div>
                                    Item
                                    <div class="uk-navbar-subtitle">Subtitle</div>
                                </div>
                            </a>
                        </li>
                    </ul>
    
                </div>
    
            </div>
        </div>
    </nav>

内容项

您还可以向导航栏添加自定义内容,例如文本、图标、按钮或表单。将 .uk-navbar-item 类添加到用作内容容器的 <div> 元素。

<nav class="uk-navbar-container" uk-navbar>
    <div class="uk-navbar-left">
        <a href="" class="uk-navbar-item uk-logo"></a>
        <ul class="uk-navbar-nav"></ul>
        <div class="uk-navbar-item"></div>
    </div>
</nav>

实用程序组件 中的 .uk-logo 类添加到 <a><div> 元素以指示您的品牌。

  • <nav class="uk-navbar-container">
        <div class="uk-container">
            <div uk-navbar>
    
                <div class="uk-navbar-left">
    
                    <a class="uk-navbar-item uk-logo" href="#" aria-label="Back to Home">Logo</a>
    
                    <ul class="uk-navbar-nav">
                        <li>
                            <a href="#">
                                <span class="uk-icon uk-margin-small-right" uk-icon="icon: star"></span>
                                Features
                            </a>
                        </li>
                    </ul>
    
                    <div class="uk-navbar-item">
                        <div>Some <a href="#">Link</a></div>
                    </div>
    
                    <div class="uk-navbar-item">
                        <form action="javascript:void(0)">
                            <input class="uk-input uk-form-width-small" type="text" placeholder="Input" aria-label="Input">
                            <button class="uk-button uk-button-default">Button</button>
                        </form>
                    </div>
    
                </div>
    
            </div>
        </div>
    </nav>

您可以创建一个带有居中徽标的分裂菜单。只需在同一个导航栏容器中将 uk-navbar-center-left 类添加到一个导航栏,将 uk-navbar-center-right 类添加到另一个导航栏即可。这将使您的徽标保持居中,并将菜单对齐到左侧和右侧。

<div class="uk-navbar-container" uk-navbar>
    <div class="uk-navbar-center">
        <div class="uk-navbar-center-left">…</div>
        <a href="" class="uk-navbar-item uk-logo"></a>
        <div class="uk-navbar-center-right">…</div>
    </div>
</div>
  • <nav class="uk-navbar-container">
        <div class="uk-container">
            <div uk-navbar>
    
                <div class="uk-navbar-center">
    
                    <div class="uk-navbar-center-left">
                        <ul class="uk-navbar-nav">
                            <li class="uk-active"><a href="#">Active</a></li>
                            <li>
                                <a href="#">Parent</a>
                                <div class="uk-navbar-dropdown">
                                    <ul class="uk-nav uk-navbar-dropdown-nav">
                                        <li class="uk-active"><a href="#">Active</a></li>
                                        <li><a href="#">Item</a></li>
                                        <li><a href="#">Item</a></li>
                                    </ul>
                                </div>
                            </li>
                        </ul>
                    </div>
                    <a class="uk-navbar-item uk-logo" href="#">Logo</a>
                    <div class="uk-navbar-center-right">
                        <ul class="uk-navbar-nav">
                            <li><a href="#">Item</a></li>
                            <li><a href="#">Item</a></li>
                        </ul>
                    </div>
    
                </div>
    
            </div>
        </div>
    </nav>

切换项

.uk-navbar-toggle 类和 uk-navbar-toggle-icon 属性添加到 <a><div> 元素以创建用作切换的图标。默认情况下,没有 JavaScript 附加到切换。例如,您可以添加来自 画布组件 的画布导航或来自 模态框组件 的模态框。

<div class="uk-navbar-container" uk-navbar>
    <div class="uk-navbar-left">
        <a class="uk-navbar-toggle" uk-navbar-toggle-icon href=""></a>

下拉栏

下拉栏会扩展到导航栏的整个宽度,并显示下拉菜单,而不会显示其默认样式。若要将下拉菜单放置在这样的下拉栏内,请将 dropbar: true 选项添加到 uk-navbar。或者,使用 dropbar-anchor 选项来选择在哪个元素之后将下拉栏注入标记中。

<nav class="uk-navbar-container" uk-navbar="dropbar: true">…</nav>
  • <div class="uk-position-relative">
    
        <nav class="uk-navbar-container">

宽度和网格

您可以在下拉菜单中放置来自 网格组件 的网格。只需使用 <div> 元素包装内容,并添加 uk-grid 属性。如果网格在下拉菜单不再适合其容器时应该自动堆叠,只需添加 .uk-drop-grid 类即可。

若要容纳多达五列,您还需要添加以下类之一。如果列不再适合容器,则列会堆叠。

描述
.uk-navbar-dropdown-width-2 添加此类以将下拉菜单的宽度加倍。
.uk-navbar-dropdown-width-3 添加此类以将下拉菜单的宽度增加三倍。
.uk-navbar-dropdown-width-4 添加此类以将下拉菜单的宽度乘以四。
.uk-navbar-dropdown-width-5 添加此类以将下拉菜单的宽度乘以五。

对于基本的粘性导航栏,请将导航栏包装在一个具有来自 粘性组件uk-sticky 属性的容器中。

导航栏本身具有一个修饰符类 uk-navbar-sticky,它确保粘性状态的优化样式(例如,额外的框阴影)。若要让粘性组件动态添加和删除该类,请设置 cls-active: uk-navbar-sticky。若要确保将该类添加到导航栏容器,请设置 sel-target: .uk-navbar-container

注意 您可以在 粘性导航栏 的测试中查看更多示例。

<div uk-sticky="sel-target: .uk-navbar-container; cls-active: uk-navbar-sticky">
    <nav class="uk-navbar-container" uk-navbar></nav>

透明粘性导航栏

透明导航栏 变为粘性时,通常需要删除 .uk-navbar-transparent 类以及 .uk-light.uk-dark,并在导航栏恢复到非粘性状态时重新添加它们。为此,请设置 cls-inactive: uk-navbar-transparent uk-light

默认情况下,立即切换类看起来并不理想。相反,请设置 start: 200 以便在用户滚动经过导航栏 200 像素后使导航栏消失,然后重新出现。在这种情况下,导航栏也可以使用动画滑动进来。只需设置 animation: uk-animation-slide-top 即可。

<div uk-sticky="start: 200; animation: uk-animation-slide-top; sel-target: .uk-navbar-container; cls-active: uk-navbar-sticky; cls-inactive: uk-navbar-transparent uk-light">
    <nav class="uk-navbar-container uk-light" uk-navbar></nav>

下拉栏透明模式

若要优化透明导航栏在打开下拉栏时的外观,请将 dropbar-transparent-mode 选项设置为以下值之一。

模式 描述
remove 在下拉栏打开时删除导航栏透明度,并在下拉栏关闭时添加透明度。
behind 在导航栏后面打开下拉栏,以便导航栏内容显示在下拉栏背景之上。

使用 反转组件 根据后面的背景颜色为透明导航栏着色。若要防止导航栏在停止透明时改变颜色,只需将 sel-active: .uk-navbar-transparent 选项添加到 uk-inverse 属性即可。

例如,如果导航栏仅在英雄区是透明的,但在粘性状态下不是,则设置 dropbar-transparent-mode: remove

<div uk-sticky="start: 200; animation: uk-animation-slide-top; sel-target: .uk-navbar-container; cls-active: uk-navbar-sticky; cls-inactive: uk-navbar-transparent">
    <nav class="uk-navbar-container" uk-inverse="sel-active: .uk-navbar-transparent" uk-navbar="dropbar: true; dropbar-transparent-mode: remove">…</nav>
</div>

或者,如果导航栏即使在粘性状态下也始终是透明的,则设置 dropbar-transparent-mode: behind 以在导航栏后面打开下拉栏,使其不再透明。

在使用粘性透明导航栏时,它通常会与页面背景混合。在这种情况下,需要使用 dropbar-anchor 将下拉栏放置在混合元素之外,并将下拉菜单放置在 container 之外。否则,下拉栏和下拉菜单也会与页面背景混合。这也意味着下拉栏将放置在粘性容器之外。因此,只有导航栏会保持粘性,打开的下拉栏会滚动到视图之外。这就是为什么我们在下拉栏中添加了新的 close-on-scroll 选项以在滚动之前关闭下拉栏。

由于只有白色与页面背景混合效果良好,因此请确保导航栏具有浅色,或使用 .uk-light 类。不要使用 uk-inverse 属性来自动为导航栏着色。

分别为导航栏部分着色

若要分别为导航栏部分着色,只需将 target: .uk-navbar-left, .uk-navbar-center, .uk-navbar-right 选项添加到 uk-inverse 属性即可。

<div class="uk-position-relative">

    <div class="uk-position-top">
        <div uk-sticky="sel-target: .uk-navbar-container; cls-active: uk-navbar-sticky">

        </div>
