 # Customizing the Preview Pane

     ### Lists and Objects
     The API for accessing the individual fields of list- and object-type entries is similar to the API
     for accessing fields in standard entries, but there are a few key differences. Access to these
     nested fields is facilitated through the `widgetsFor` function, which is passed to the preview
     template component during render.
-    
     **Note**: as is often the case with the NetlifyCMS API, arrays and objects are created with
     Immutable.js. If some of the methods that we use are unfamiliar, such as `getIn`, check out
     [their docs](https://facebook.github.io/immutable-js/docs/#/) to get a better understanding.

     ### Accessing Metadata
     Preview Components also receive an additional prop: `fieldsMetaData`. It contains aditional information (besides the plain plain textual value of each field) that can be useful for preview purposes. 
-    
     For example, the Relation widget passes the whole selected relation data in `fieldsMetaData`.
-    
     ```js
     export default class ArticlePreview extends React.Component {
       render() {
         const {entry, fieldsMetaData} = this.props;
         const author = fieldsMetaData.getIn(['authors', data.author]);

       }
