I have a choice set with Id = menu and I want to make sure that they select at least two items from that choice set.

I have tried multiple ways to display a message if they select less than 2 but it doesn't work. Can anyone tell me if I can accomplish what I am trying and what the correct syntax might be:

 {
            "type": "Input.ChoiceSet",
            "choices": [
                {
                    "title": "Potato",
                    "value": "Potato"
                },
                {
                    "title": "Salad",
                    "value": "Salad"
                },
                {
                    "title": "French Fries",
                    "value": "French Fries"
                },
                {
                    "title": "Carrots",
                    "value": "Carrots"
                },
                {
                    "title": "Soup",
                    "value": "Soup"
                }
            ],
            "isRequired": true,
            "id": "menuSelection",
            "label": "Select at least 2:",
            "isMultiSelect": true,
            "errorMessage": "At least 2 are required"
        },
        {
            "type": "TextBlock",
            "text": "Please select at least 2 items above",
            "isVisible": "${if(countSelectedItems[menuSelection]>1,true,false)}"
            "wrap": true
        }

Hello,

You should check that in any of the action you may have (like submit). Have a look at this sample:

{
  "$schema": "http://adaptivecards.io/schemas/adaptive-card.json",
  "type": "AdaptiveCard",
  "version": "1.3",
  "body": [
    {
      "type": "TextBlock",
      "text": "Please select at least two options:",
      "wrap": true
    },
    {
      "type": "Input.ChoiceSet",
      "id": "choiceSet",
      "isMultiSelect": true,
      "style": "expanded",
      "choices": [
        {
          "title": "Option 1",
          "value": "1"
        },
        {
          "title": "Option 2",
          "value": "2"
        },
        {
          "title": "Option 3",
          "value": "3"
        },
        {
          "title": "Option 4",
          "value": "4"
        }
      ]
    }
  ],
  "actions": [
    {
      "type": "Action.Submit",
      "title": "Submit",
      "data": {
        "minSelection": 2
      }
    }
  ]
}

There's a "data" attribute and setting the "minSelection" to 2.

Hope that helps!
