I have the bot which working in MS Teams channel. I use it for creating some FTP groups and other stuff. The key problem, that now i have the large number of that groups and i wanna to filter them, before creating a new one. Is it possible to implement autocomplete for input text-box? I'm trying to use input choice set as a drop down list, but is not good solution, because I have about 200-300 groups, and its very annoying to scroll them down. If you have any solutions, please share it!:)
This is not possible yet. The Adaptive Cards roadmap can be found here.
What you are looking for is 'dynamic searchable select menu (like select2), which is on the roadmap, but currently not planned.
