## Overview
The Column Data widget is designed to display data from another record in a source. It differs from the [Column Citation](https://docs.labii.com/widgets/column-widgets/column/column-citation) widget as it saves a copy of the data in the widget for quick loading. This widget is particularly useful for displaying text-type data, and it can be automatically updated to reflect changes in the source.
## Use case
1. Stock checkout: Display the same unit as the stock using the Column Data widget.
## Configuration
To enable the widget's functionality, it requires the provision of options. Each option comprises the following fields:
* **Source column**: Select one of the ForeignKey columns to define the data source.
* **Field**: Choose the field you want to display.
* **Stop condition:** The formula will stop calculation when the condition is met. It must return a `true` or `false` value. This field does not support other column data, you can only use the variable `data` to reference the current record data.
* **Should auto update**: If checked, the widget will reload data from the source.
* **Should auto update when readonly** - If checked, this widget will perform a live calculation when readonly.
### Examples:
```json
{
"column": {"sid":"", "name":""},
"field": "name",
"should_auto_update": false,
"stop_condition": "data !== \"\""
}
```
