Each element in the editor represents a data field in the store. For example, when you choose PRODUCT_NAME, it will automatically use the product name as the data source for the specified element position when creating the label. You can find more information here about the supported data field types.
As shown in the illustration below, setting it up in this manner will fetch product data from the store and display it on the label.
Furthermore, we have the ability to add fixed text to the label along with connecting it to the date column. You can choose to set "Link to" as "CUSTOM_TEXT" in order to input details such as the company name or any note on the labels.
