样式自己调整

表单结构自定义

<!--{iCMS:forms:create formid="表单ID" layout="false"}-->

其它字段只要name跟自定义的一样就可以
示例:

<div class="form-body">
    <!--自构表单-->
    <form action="<!--{iCMS:router url='forms'}-->" method="post">
        <!--{iCMS:forms:create formid="表单ID" layout="false"}-->
        <!--表单结构-->
        <input id="自定义表单字段1" name="自定义表单字段1" type="text" class="form-control" value="" />
        <input id="自定义表单字段2" name="自定义表单字段2" type="text" class="form-control" value="" />
        <input id="自定义表单字段3" name="自定义表单字段3" type="text" class="form-control" value="" />
        <div class="form-actions">
            <button class="btn btn-lg btn-primary" type="submit">
                <i class="fa fa-check"></i> 提 交
            </button>
        </div>
    </form>
</div>
