In the same context i have another query 

```
<select multiple="multiple" name="prodSKUs">
            <c:forEach items="${productSubCategoryList}" var="productSubCategoryList">
          <option value="${productSubCategoryList}"${productSubCategoryList == productSubCategoryName ? 'selected' : ''}>${productSubCategoryList}</option>
         </c:forEach>
        </select>

```

and the corresponding setting in request is like

```
for(int i=0;i<userProductData.size();i++){
    String productSubCategoryName=userProductData.get(i).getProductSubCategory();
    System.out.println(productSubCategoryName);
    request.setAttribute("productSubCategoryName",productSubCategoryName);

}

```

here i have multiple select drop down ,even though i get the return value from for as two ,in the UI only one data is getting higlighted not the second one,What is wrong in the code ?
