如何使项目浮动在 Jquery 对话框之外

我想要一个看起来像这样的对话框：

我认为这种方法可行，但我想我错了：

JavaScript

//Creates The Dialog
$('.ImageDialogDiv').dialog({
    position: [98, 223],
    resizable: false,
    //modal: true,   /* UNCOMMENT AFTER DEBUGGING */
    closeOnEscape: false,
    class: 'OverwriteDialogOverflow',
    title: $('#hiddenDialogElements').html(),
    open: function (event, ui) { $(".ui-dialog-titlebar-close").hide(); }
});

CSS

  /*
  * Overrides hidden overflow
  */
 .OverwriteDialogOverflow
 {
     overflow: visible;
 } 

HTML

<div id = "dialogDiv" class = "ImageDialogDiv"></div>

<div id = "hiddenDialogElements">
    <button id = "hiddencloseButton">Close</button>
    <div id = "hiddenArrowButtons">
        <button class = "ArrowButtonDialogLeft" onclick = "ShowNextImage(-1)" ></button>
        <button class = "ArrowButtonDialogRight" onclick = "ShowNextImage(1)" ></button>
    </div>
</div>

当我尝试将箭头或关闭按钮移出对话框时，就会被切断并且不可见。我想添加.OverwriteDialogOverflow会解决这个问题的。

建议？

如果/当您更新帖子时，我将对此进行更详细的编辑，但我要做的是将对话框和按钮放在具有相对定位的容器 div 中，并使用绝对定位来放置按钮。像下面这样的东西...

HTML：

    <div id = "hiddenDialogElements">
        <button id = "hiddencloseButton">Close</button>
        <div id = "hiddenArrowButtons">
            <button class = "ArrowButtonDialogLeft" onclick = "ShowNextImage(-1)" ></button>
            <button class = "ArrowButtonDialogRight" onclick = "ShowNextImage(1)" ></button>
        </div>
    </div>
</div>

CSS:

.OverwriteDialogOverflow { overflow: visible; }

#dialogContainer { position: relative; }

#hiddencloseButton {
    position: absolute;
    top: -15px;
    right: -15px;
}

#hiddenArrowButtons {
    position: absolute;
    bottom: -30px;
}

.ui-dialog { overflow: visible; }

Edit:根据评论添加了 .ui-dialog CSS
