我有一个显示一些数据的 Dgrid，比如 DataDgrid。我想在主 DataDgrid 的一个单元格内添加一个基于另一个 Dgrid 的选择控件，比如 SelectDgrid。
要添加选择，我将遵循此示例：http ://dojofoundation.org/packages/dgrid/tutorials/drop_down/
我准备了一个 JSFiddle，表明它可以工作：http: //jsfiddle.net/amiramix/qqezJ/
现在，当我尝试添加选择时，它显示在表格单元格内，而不是浮动在主 DataGrid 上。请检查此 JSFiddle（单击编辑以将选择添加到主 DataGrid）：http: //jsfiddle.net/amiramix/qqezJ/5/
我猜它归结为一些 CSS 设置不正确。我试图摆弄 z-index 但没有任何结果。任何帮助将不胜感激。
添加以下代码以消除 stackoverflow 的警告：
HTML：
<button id="editButton" type="button">Edit</button>
<div id="grid"></div>
CSS：
#grid {
line-height: 30px;
}
.mySelect {
border: 1px solid #b5bcc7;
background-color: #ffffff;
height: 17px;
/* Make this position: relative so our arrow is positioned within */
position: relative;
padding: 0;
}
.mySelect .label {
line-height: 17px;
vertical-align: middle;
}
.mySelect .arrow {
/* Position the arrow on the right-hand side */
position: absolute;
top: 0;
right: 0;
/* Use claro's arrow image */
background-image: url("https://ajax.googleapis.com/ajax/libs/dojo/1.8.1/dijit/themes/claro/form/images/commonFormArrows.png");
background-position: -35px 70%;
background-repeat: no-repeat;
/* 16x16 with a white border and a gray background */
width: 16px;
height: 16px;
border: 1px solid #ffffff;
border-top: none;
background-color: #efefef;
}
.mySelect .dgrid {
position: absolute;
top: 17px;
left: -1px;
width: 100%;
display: none;
}
.mySelect .opened {
display: block;
}
