## Overview
The Labii Column Citation widget functions similarly to the [Record Citation](https://docs.labii.com/widgets/column-widgets/column/record-citation) tool, offering a convenient method to exhibit columns from a linked record that are specified by ForeignKey columns. This widget provides users within the Labii platform an efficient means to showcase and utilize data stored in interconnected records, facilitating a seamless display of relevant column information across linked records.
## Use case
1. Display the unit of a checkin record from stock.
## Configuration
To enable the widget's functionality, it requires the provision of options. Each option comprises the following three fields:
* **Source column** - To define the data source, select one of the ForeignKey columns.
* **Index** - The index of the Unique Code within the source column. If multiple Unique Codes are defined in the configuration of the source column, specify an index number to indicate which Unique Code to use. Defaults to 1.
* **Fields** - You can choose one or more fields to display.
* **Should display header** - The headers of the fields will be displayed if you check this box.
