The add menu tag creates an add menu button for one or multiple items. It’s
used for actions that add entities (e.g. a new blog entry), and is part of the
Management Bar. Use the <liferay-frontend:add-menu> tag to create the add
menu and nest a <liferay-frontend:add-menu-item> tag for each item.
When the menu has one item, the button triggers the item’s action as shown in the example below for the Blogs Admin App:
<liferay-frontend:management-bar-buttons>
...
<liferay-frontend:add-menu
inline="<%= true %>"
>
<liferay-frontend:add-menu-item
title='<%= LanguageUtil.get(request, "add-blog-entry") %>'
url="<%= addEntryURL %>"
/>
</liferay-frontend:add-menu>
</liferay-frontend:management-bar-buttons>
Figure 1: The add button pattern consists of an `add-menu` tag and at least one `add-menu-item` tag.
When the menu has multiple items, they display in a pop-up menu. For example, the Message Boards Admin application has the configuration below:
<liferay-frontend:add-menu>
...
<liferay-frontend:add-menu-item title='<%= LanguageUtil.get(request,
"thread") %>' url="<%= addMessageURL.toString() %>" />
...
<liferay-frontend:add-menu-item title='<%= LanguageUtil.get(request,
(categoryId == MBCategoryConstants.DEFAULT_PARENT_CATEGORY_ID) ?
"category[message-board]" : "subcategory[message-board]") %>'
url="<%= addCategoryURL.toString() %>" />
...
</liferay-frontend:add-menu>
Figure 2: The add button pattern consists of an `add-menu` tag and at least one `add-menu-item` tag.
The examples above use some of the available attributes. See the add menu and add menu item taglibdocs for the full list of available attributes for the tags.
