title: Radio Group in ExtJS Editor Grid/Grid
body: <p>I need radio group in extjs grid. I can have the radiogroup as editor but users wants to directly select the option from radio.</p>
  
  <p>e.g.
  O yes O no O maybe</p>
  
  <p>instead of having yes as by default and once they select the cell, it gets converted to radio group (like how the editor grid works), they wants the default behavior as this options. (They dont want the drop down)</p>
