How do I set a custom field as required ?

You can easily set a custom field as a required field by following bellow steps.

1. Open the Checkout Extensions app from your Shopify admin, then click on “Extensions” in the app navigation menu.

2. On the Extensions page, Find or use the search bar to find the Multi line text field extension, then click the Manage button to access and customize its settings.

5. Click on “Open checkout editor”. You’ll be redirected to the Checkout Editor, where you can add this extension to your checkout page.

6. In the Checkout Editor, locate the Checkout Extensions app. From the available blocks, add the “Multi line text field” block to your checkout page layout.

7. After adding the Multi line text field , open its settings. Scroll down to the “Required” setting and select “Required” from the dropdown. Once you've made the selection, click Save to apply the changes.

   Your extension will now be live on the checkout page.

Note: To display the extensions on your live store, make sure you are on the Premium Plan of Checkout Extensions. Merchants on the Free Plan can configure upsell settings, but the upsell will not appear on the live checkout page until the Premium Plan is active.
