# Displaying hierarchical information from SharePoint list

## Summary 

At the time of developing this sample, the Office 365 UI fabric does not have any control for displaying hierarchical information. This web part helps to display the hierarchical information from SharePoint list.

![Web part preview][figure1]

The web part is configured to render the mock data when added to the local SharePoint workbench. 
![Local SharePoint Workbench Run][figure2]

When added to SharePoint site, the source list containing hierarchical information can be configured from web part properties.
The sample also provisions the list called “Hierarchy” which can be used as an example to start using the web part.

### SharePoint Asset

A SharePoint list (named Hierarchy) is provisioned to store the hierarchical data. The schema of the list is as below.
