Can I add a contact to a group right from All Contacts?

Add contacts to a group

1. In the Contacts app  on your Mac, select contacts.
2. Drag the selected contacts to a group in the sidebar.
3. If the contacts don’t go into the group, check the group—you can’t add contacts to a Smart Group.

If you use an Exchange account in Contacts, those contacts can belong to only one folder at a time. Any contacts that aren’t in a folder you create are in the default Exchange Contacts folder.

Email a group of contacts in Contacts on Mac

n the Contacts app  on your Mac, do either of the following:

• Control-click a group in the sidebar, then choose Send Email. A new email opens in the Mail app, addressed to the group.
• Drag a group from the sidebar to an address field in an email you’re writing.
• In your email, either the group name or individual contact names are shown, depending on how Composing preferences are set in Mail.
• If the group is shown in your email but you want to see the contacts instead, click the arrow next to the group name, then choose Expand Group.

I have always been wondering why the native iOS 8 / iOS 9 / iOS 10 / iOS 11 contacts app does not have an intuitive option to add a contact to a group on iPhone and iPad. The solution is either to do a more or less uncomfortable work-around, use the iOS app ‘Simpler Contacts’ or, for iCloud groups only, add the contact via iCloud on a web browser.

If you want to add a NEW contact directly to a group in IOS:

choose Groups and then uncheck all.

Then tap on group you want to add it to.

Tap Done.

Tap + and make the new contact.

Remember to check all again when finished.

Now I need to figure out how to make a NEW group in IOS

OK good luck. :)

I think the iPad was designed by a committee to take the best of the Mac & the best of the iPhone, mingle them & end up with the worst of both.

Thanks! :)
