I tried to find out some solution, but no result,
may be you can write an email to data-shapes for fixing this issue in next package version,
But you can change your input style as per current available solution,
As you wanted to do conditional input,
Currently in the same pop-up window you are providing conditional input (In which we are facing some UI Problem)
So you can have 2 pop-up UI window for selection and 2nd pop-up UI window will depend upon the selection of 1st popup.
