${id.index} ${keyword}

 Traverse the elements after the first element in the List collection (excluding the first element):
${id.index} ${keyword}

Two layers of List traversal

<%List list = new ArrayList();List list1 = new ArrayList();List list2 = new ArrayList();list1.add("1-a");list1.add("1-b");list2.add("2-d");list2.add("2-c");list.add(list1);list.add(list2);request.setAttribute("list1", list1);request.setAttribute("list", list);%>${item2 }

Copy
