设置在线商店中的下拉菜单
您可以使用下拉菜单将产品、产品系列或页面组合在一起，以便客户更轻松地浏览您的在线商店。例如，如果您有很多产品，那么您可能想要将它们添加到产品系列中，然后使用主菜单中的下拉菜单来整理产品系列。这可以帮助客户找到他们想要的产品类型。
您还可以添加、删除或编辑下拉菜单或在线商店的默认菜单中的菜单项。
您可以从 Shopify 后台的网站地图页面中查看和更改在线商店网站地图。
嵌套菜单项以开发下拉菜单
您可以通过创建或移动菜单项来开发下拉菜单，使它们“嵌套”在顶级项之下。顶级项显示在在线商店的主菜单中，而嵌套菜单项显示在下拉菜单中。顶级项最多可以有两级嵌套下拉菜单：
所有模板均会将嵌套项显示为主菜单中的下拉菜单，部分模板会将嵌套项显示为其他地点中的下拉菜单。
在线商店中主菜单和下拉菜单的外观和地点取决于在线商店的模板。某些模板会在主菜单中的下拉菜单名称旁边显示一个图标，帮助客户意识到此处有下拉菜单。
您可以从主菜单中的任何菜单项添加下拉菜单。

Set up drop-down menus in your online store
You can use drop-down menus to group products, collections, or pages together and make it easier for customers to navigate your online store. For example, if you have a lot of products then you might want to add them to collections and then use a drop-down menu from the main menu to organize the collections. This can help a customer to find the type of products that they're looking for.
You can also add, remove, or edit menu items in drop-down menus, or in your online store's default menus.
You can view and change your online store navigation from the Navigation page in your Shopify admin.
Nesting menu items to build drop-down menus
You can build drop-down menus by creating or moving menu items so that they are "nested" below a top-level item. The top-level item appears in the main menu on your online store, and the nested menu items appear in a drop-down menu. The top-level item can have up to two levels of nested drop-down menus:
All themes will display nested items as drop-down menus from the main menu, and some themes will display nested items as drop-down menus in other locations.
The appearance and location of the main menu and drop-down menus in your online store depend on your online store's theme. Some themes will display an icon beside the name of a drop-down menu in the main menu to help customers recognize that a drop-down menu is there.
You can add a drop-down menu from any of the menu items in the main menu.
