Decimal Rating Component

Yes. But not directly as Appian has a half-star icon but not a mirror image of it. 

So one way to do it is to let the user click once to fill half star and click twice to fill the entire star. Or, just give them a list of options when adding the rating along a representation of how many stars they are rating and show that rating using the styled icons. 

Hey Harshit , Yeah i was thinking the same way but the thing is how to control the user click options.(how to made it selectable twice)

  local!index,
