Group Radio Element and Dependent/Dynamic Form Element

I have 2 queries:

  1. How can I show images as Radio Group
  2. Load form element based on previous value selection

e.g. if i select a facility 'x' then i should be presented 'a,b,c' package options only which belong to facility x.

This question sounds like it might be better suited for StackOverflow. What you're asking would generally be accomplished on the client-side, rather than on the server.

I am using Phalcon Forms to achive this.

Fair enough - #1 might have a Phalcon answer. #2 is commonly solved by doing some DOM switching with Javascript on the client-side, not on the server-side.
