Conditional text fields

[iw-ezequiel]

Hi, we're considering some further applications of X-Gov-Forms at UKHSA, and a nice feature would be conditional text fields. For example, a text field only appears if I've answered "yes" or "no" to a previous question, so that I can expand on the answer. At the moment it does not appear as though this is possible on text fields. Am I correct, and if so is there any obvious limitation? Thanks!
