+The following describes how to traverses in mustache.js and javascript.
+
+### First Option
+
+```js
+class List extends Omi.Component {
+    constructor(data) {
+        super(data);
+    }
+
+    render () {
+        return `<div>
+                    <ul> {{#items}} <li id="{{id}}">{{text}}</li> {{/items}}</ul>
+                </div>`;
+    }
+}
+
+Omi.render(new List({
+    items: [
+        {id: 1, text: 'Omi'},
+        {id: 2, text: 'dntzhang'},
+        {id: 3, text: 'AlloyTeam'}
+    ]
+}),"body");
+```
+
+Mustache.js more detailed loop traversal use can see 
+
+For more details for traversal in mustache.js please view [https://github.com/janl/mustache.js#non-empty-lists](https://github.com/janl/mustache.js#non-empty-lists).
+
+For example, it also support:
+

+
+### Second Option
+
+```js
+class List extends Omi.Component {
+    constructor(data) {
+        super(data);
+    }
+
+    render() {
+        return `<div>
+                    <ul>
+                    ` + this.data.items.map(item =>
+                        '<li id="' + item.id + '">' + item.text + '</li>'
+                    ).join("") + `
+                    </ul>
+                </div>`;
+    }
+}
+
+Omi.render(new List({
+    items: [
+        {id: 1, text: 'Omi'},
+        {id: 2, text: 'dntzhang'},
+        {id: 3, text: 'AlloyTeam'}
+    ]
+}),"body");
+```
+
+Of course, you can also use template string inside the `map`
+
+```js
+...
+render() {
+    return `<div>
+                <ul>
+                ` + this.data.items.map(item =>
+                    `<li id="${item.id}">${item.text}</li>`
+                ).join("") + `
+                </ul>
+            </div>`;
+}
+...
+```
