Не могли бы вы попробовать добавить кнопки внутри разных столбцов в разных наборах столбцов? Я попробовал ниже json, и он работал для меня:
{
"type": "AdaptiveCard",
"version": "1.0",
"body": [
{
"type": "ColumnSet",
"columns": [
{
"type": "Column",
"width": "stretch",
"items": [
{
"type": "ActionSet",
"actions": [
{
"type": "Action.Submit",
"title": "Action.Submit"
}
]
}
]
}
]
},
{
"type": "ColumnSet",
"columns": [
{
"type": "Column",
"width": "stretch",
"items": [
{
"type": "ActionSet",
"actions": [
{
"type": "Action.Submit",
"title": "Submit action 2"
}
]
}
]
}
]
},
{
"type": "ColumnSet",
"columns": [
{
"type": "Column",
"width": "stretch",
"items": [
{
"type": "ActionSet",
"actions": [
{
"type": "Action.Submit",
"title": "Submit action3"
}
]
}
]
}
]
}
],
"$schema": "http://adaptivecards.io/schemas/adaptive-card.json"
}
