I'm creating one block, there would be a total of main 5 Radiobuttons and each Radiobutton will be having 1 Sub Radiobutton.

Radiobutton's features and functionalities

-Radio buttons will have text on them.

-When we click any main Radio button it should show its sub radio button with a label on it and the rest of the main Radio buttons should hide

    -Only visible main radio buttons will be on which you have click and rest should hide and doesn't show on the screen

   -When radio buttons are active it must have a cross icon/button to close it 

Editor's Functionality

An editor should have the power to add content/label to all main radio buttons and their respective sub-radiobuttons.
