HR P&F: Hide/Show button dynamically

Dear Experts

I've a requirement in FPM form type to show/hide button based on drop-down list in other field. There is a similar discussion HR P&F: Call BS from list screen(F4) where Christopher Solomon helped me to dynamically change drop-down value w.r of another field.

Similarly I need an another help to hide/show a button & text-view label based on drop-down list of another field. Kindly refer the screenshot for your ref.

Thanks
