A window will popup showing the available settings. Click on the switch on the left of the label Pricing Rows are Optional, the switch will turn green to indicate this feature is activated and the price line items are now optional.
Next you need to choose if you would like the recipient to choose only one price line, or more than one line item.
After you have switched on the Pricing Rows are Optional feature, you will see a toggle switch appear on the right, it will default to the setting Single Choice. If you would like the recipient of the sales quote to choose only one price line item in the group, then leave the toggle switch on the Single Choice setting.
If you would like the recipient of the sales quote to choose more than one price line item, then click on the toggle switch to the setting Multiple Choice.
Click on the Save button to commit your changes and close the window.
You will now see a check box (or a radio button) next to your price line items grouped under the sub-heading.
If you would like to set one of the price line item as the default choice, simply click on the checkbox/radio button next to the line item that will be the default choice. Otherwise leave them all unselected.
Click on the Save and Preview button to see the price table with optional price line items.
