I have some cards in carousel in a bot-framework chatbot.
It shows texts and buttons.
Some text are longer than the rest, so the card is not the same height.
Is there a way to make them to be the same size?
You can almost do this. You can set a minimum height in pixels, but if you have Wrap turned on, sufficiently large blocks of text can still push past this minimum height. There is no way to set a maximum height (though you can kind of do this by removing Wrap on all your text elements so that you know they'll only take 1 line. Not very readable, though). To do this just add a minHeight element to the top level of the card definition, e.g.
{
"$schema": "http://adaptivecards.io/schemas/adaptive-card.json",
"version": "1.3",
"minHeight": "400px",
"type": "AdaptiveCard",
"body": [
// card content here
]
}
Note that you can test this out in Adaptive Card Designer to make a a little easier to see the impact of your changes and various sized text fields.
