I needed something similar  the ability to click on a set of icons to indicate a choice  or a text-based choice and have that update the model  2-way-binding  with the represented value and to also a way to indicate which was selected visually  I created an AngularJS directive for it  since it needed to be flexible enough to handle any HTML element being clicked on to indicate a choice    lt ul ng-repeat  vote in votes      gt       lt li data-choice  selected  data-value  vote id  gt     lt  li gt   lt  ul gt    Solution   http   jsfiddle net brandonmilleraz 5fr9V

Each row has an ID  All you have to do is to send this ID to the function setSelected    store it  in  scope idSelectedVote for instance   and then check for each row if the selected ID is the same as the current one  Here is a solution  see the documentation for ngClass  if needed     scope idSelectedVote   null   scope setSelected   function  idSelectedVote        scope idSelectedVote   idSelectedVote        lt ul ng-repeat  vote in votes  ng-click  setSelected vote id   ng-class   selected  vote id     idSelectedVote   gt           lt  ul gt    Plunker

You probably want to have LI rather than the UL have the background-color    selected li     background-color  red      Then you want to have a dynamic class for the UL    lt ul ng-repeat  vote in votes  ng-click  setSelected    class    selected    gt    Now you need to update the  scope selected when clicking the row    scope setSelected   function        console log  show   arguments  this      this selected    selected       and then un-select the previously highlighted row    scope setSelected   function           console log  show   arguments  this      if   scope lastSelected          scope lastSelected selected               this selected    selected       scope lastSelected   this      Working solution   http   plnkr co edit wq6nxc p preview
