AngularJs filtering data based on option selection and tag creation based on selection

Question

Here is my code : Jsfiddle

1. Initialy its should display all the data.

2. I'm able to add new tags and based on tag selection data is filtering but data should be added below the existing filtered data if new tag is selected and data should be removed if tag is deleted.

Answer 1

finally Everything is resolved.

//FILTER

    .filter('findobj', function () {
     return function (dataobj, multipleVlaue) {
         if (!multipleVlaue) return dataobj;
         return dataobj.filter(function (news) {
             var tofilter = [];

             angular.forEach(multipleVlaue,function(v,i){ 
              tofilter.push(v);
             });

             return news.CategoryList.some(function (category) {
            return tofilter.indexOf(category.DisplayName)>-1;
         });

         });
     };
     })
