问题
I am looking to develop an Adaptive card that will take a user input value ranging from 1 to 5 depending on the number of stars the user selects.
I also would like to apply animation as the user hovers over the stars. For example if the user hovers through from left to right to the 4th star then I would like stars 1 to 4 selected. Similarly, if the user hovers back left to the 2nd star then I would like the 3rd and 4th star deselected. See the link below for an example.
However, given adaptive cards are purely declarative (i.e. no code is allowed) is it possible to develop one? If so please can you point me in the right direction?
See link below for an example of how I would like this presented to a user (to be clear using Adaptive cards),

There was a question very similar to this just yesterday - see In bot framework v4, how to implemente rating card with comment box and submit button. Very important - note the comments below the answer as we had an important discussion that might also be applicable to your scenario
