[#assign componentResult = stack.findValue('getLearnData("learnCourseItem","getCourseComponentsConfig","${countConditions}")') /]
[#assign menus = (componentResult.data.menus)![] /]


		[#list menus as menu]

				[#if (menu.code == "homework")]
					[#if (result.data.get(menu.id)) ?? && ((result.data.get(menu.id))?number> 0)]
					<li class="nav_li" id="homework_main_menu">
						<a id="homework_menu_button" href="/go.html?url=${base}/learn/homework/blue/index.action?						params.courseId=${(params.courseId)!''}¶ms.columnTypeId=${(menu.id)!''}"  						target="mainContent">${(menu.name)!"全部作业"}</a>
					</li>
