1.最简单的方法，不是循环出来的

<ul class="clearfix">
        <li class="active"><a href="{:url('index/index')}">HOME</a></li>
        <li><a href="{:url('single/company')}">COMPANY</a></li>                      
        <li><a href="{:url('product/list')}">PRODUCTS</a>        
            <ul class="suMen">        
                <li><a href="{:url('product/list')}">Plastic Bottle</a></li>   
                <li><a href="{:url('product/list')}">Glass Bottle</a></li>     
                <li><a href="{:url('product/list')}">Vacuum Thermos Pot</a></li>      
                <li><a href="{:url('product/list')}">Stainless Steel Bottle</a></li>                                         
            </ul>        
        </li>  
        <li><a href="{:url('news/arrivals')}">NEW ARRIVALS</a></li>
        <li><a href="{:url('single/cooperation')}">COOPERATION</a></li>
        <li><a href="javascript:void(0)">CONTACTS</a>
            <ul class="suMen">        
                <li><a href="{:url('single/contact')}">Contact us</a></li>   
                <li><a href="{:url('single/contact')}"></a></li>     
                <li><a href="{:url('single/contact')}">FAQs</a></li>                                         
            </ul>    
        </li>
    </ul>

2.循环出来的

2.1

PHP判断数组下标有没有存在的方法  
array\_key\_exists("$key", $array)  
//$key 下标 $array 数组

<ul class="clearfix">
        {foreach name="Navigation" item="value"}
            <?php if(array_key_exists("child", $value)){?>
                <li>
                    <a href="{$value.link}">{$value.name}</a>
                    <ul class="suMen">
                        {foreach name="value.child" item="val"}
                            <li><a href="{$val.link}">{$val.name}</a></li>
                        {/foreach}                     
                    </ul>              
                </li>
            <?php }else{?>
                <li><a href="{$value.link}">{$value.name}</a></li>
            <?php }?>
        {/foreach}
    </ul>

2.2

<foreach name="Navigation" item="value">
        <if condition="count($value['child']) neq 0">
            <li>
                <a href="{$value.link}">{$value.name}</a>        
                <div class="sub_menu">
                    <ul class="clearfix">
                        <foreach name="value.child" item="val">
                            <li class="hoverli">
                                <a href="{$val.link}"><i class="fa fa-angle-right" aria-hidden="true"></i> {$val.name}</a>
                                <ul class="navul">
                                    <foreach name="val.child" item="va">
                                        <li><a href="{$va.link}"><i class="fa fa-angle-right" aria-hidden="true"></i> {$va.name}</a></li>
                                    </foreach>  
                                </ul>
                            </li>
                        </foreach>                     
                    </ul>
                </div>                
            </li>
        <else/>
            <li><a href="{$value.link}">{$value.name}</a></li>
        </if>
    </foreach>

2.3

{foreach name="Navigation" item="vo"}
        {if condition="$vo.pid eq 0"}
            <li><a href="{$vo.link}">{$vo.name}</a>
                <ul class="suMen">
                    {foreach name="Navigation" item="vos"}
                        {if condition="$vos.pid eq $vo.id"}
                            <li><a href="{$vos.link}">{$vos.name}</a></li> 
                        {/if}
                    {/foreach} 
                </ul>
            </li>
        {/if}
    {/foreach}
