Hey latanagpal!
Thanks for swinging by the forum. I certainly understand the need to be able to include those additional fields and have them marked as required.
When it comes to the plugin, we’ll actually be pulling in the fields that are already included in your MailChimp list, which we can then select or unselect for use with the plugin. As a result, when it comes to adding in an additional Text field, we’ll first want to include it in our MailChimp list. The article below will explain how to go about adding in those additional fields in MailChimp:
Manage List and Signup Form Fields
Once that text field is added in, we can go about marking those fields as required from within MailChimp, using that same List Fields & *|MERGE|* Tags page described in the article above. Simply check the “Required” box next to the fields you’d like to be marked as required, and they should be required for that list.
From there, open up your site’s Admin panel, hover over Settings, and select MC Setup. From there, scroll down to the Merge Variables Included heading and click Update Subscriber Form Settings, and you should see your updated list fields. There will even be an “Include” checkbox that can be used to select which fields to include.
Let us know if there are any additional questions, and we’ll be happy to help get ’em answered ??
