# msm:tree

> Render hierarchical (nested) data

`<msm:tree>` renders hierarchical data (items with nested children).

It uses an inner `<msm:template>` and can work with different sources via `mode`.

## Skeleton

```html theme={null}
<msm:tree id="tree" mode="BEAN" bean="treeServiceImpl" scope="PROTOTYPE" items="getTree()" item-name="n" children="children">
  <msm:template>
    <div>${n|title}</div>
  </msm:template>
</msm:tree>
```
