Using @mentions in adaptive cards.

[rmbucinell]

I am trying to create a card that show and notify our team who is on- call and show some basic information about the on-call users. The first iteration of this message I utilized markdown with the @mention syntax in order to notify the two individuals but also show all the useful information on the mouse-over popup.

**Primary** - <@personEmail:username1@compnay.com|Mr. Username1>
**Backup** - <@personEmail:username2@compnay.com|Mrs. Username2>cards, developer, webex, Other Collaboration Topics

But now I'm moving to adaptive cards and would like to replicate the @mention feature there as well. My card looks like this:

In the following code for the primary section I'm trying to replace the primary_user variable with with a mention and its not working. Is there a way to do this and if not is some kind of support in development?

{
    "type": "Column",
    "width": 100,
    "items": [
        {
            "type": "ColumnSet",
            "columns": [
                {
                    "type": "Column",
                    "items": [
                        {
                            "type": "Image",
                            "altText": "an image goes here",
                            "url": f"data:image/png;base64,{primary_img}",
                            "width": "35px",

                            "style": "Person"
                        }
                    ],
                    "width": "40px"
                },
                {
                    "type": "Column",
                    "items": [
                        {
                            "type": "TextBlock",
                            "text": "**Primary**",
                            "weight": "Bolder",
                            "spacing": "None"
                        },
                        {
                            "type": "TextBlock",
                            "text": primary_user,
                            "spacing": "None",
                            "horizontalAlignment": "left"
                        }
                    ],
                    "width": "stretch"
                }
            ]
        }
    ]
}

AFAIK there isn't a way to do that exactly, but you might consider the 'show sub-card' feature as a possibility (though your app would need to provide the extra data to display, e.g. the data typically found in a Webex @mention tool-tip). 

The current features of text blocks in a card comes as part of the adaptive card rendering code, which follows the spec (which does not provide any tool-tip like features for text block text markup).  Possibly Webex clients could provide a custom enhancement for this as you describe (which I think is pretty worthy of consideration.)  You can check here to vote for any existing similar suggestion and/or create a new one: https://ciscocollaboration.ideas.aha.io/

Might also be worth checking with the Webex dev support team directly: https://developer.webex.com/support
