推荐答案

如果您使用分层的数据是这样;

If you use hierarchical data like this;

[
    {
        name: "item1",
        subitems : ["subitem11","subitem12","subitem13"]
    },
    {
        name: "item2",
        subitems : ["subitem21","subitem22"]
    },
    {
        name: "item3",
        subitems : ["subitem31","subitem32","subitem33"]
    }
];

您可以使用此标记;

<select ng-model="selecteditem" ng-options="item as item.name for item in list"></select>
<select ng-model="selectedsubitem" ng-options="subitem for subitem in selecteditem.subitems"></select>
