body: <p>Below is my data source which needs to be binded to two kendo drop down list. One is for Program and another for IForm. I need the filteration to be done in the dropdown itself.</p>
  
  <pre><code>$scope.programIFormList = new kendo.data.DataSource({
          data: [
                      {
                          Name: "Program1",
                          IsProgram: "true",
                          ProgramId: 1,
                          Status: 0,
                          PatientId: 1,
                          StartDate:"",
                          EndDate:""
                      },
                      {
                          Name: "Program2",
                          IsProgram: "false",
                          ProgramId: 2,
                          Status: 0,
                          PatientId: 1,
                          StartDate:"",
                          EndDate:""
                      }
                  ]
      }); 
  </code></pre>
  
  <p>Below is html code:</p>
  
  <pre><code> &lt;div class="col-lg-2 col-md-4 col-sm-4 col-xs-4"&gt;
                      &lt;select id="patient" kendo-drop-down-list k-data-text-field="'Name'" k-data-value-field="'PatientId'"  k-data-source="patientList" &gt;                      
                      &lt;/select&gt;
                  &lt;/div&gt;
  
                  &lt;div class="col-lg-2 col-md-4 col-sm-4 col-xs-4"&gt;
                      &lt;select kendo-drop-down-list k-data-text-field="'Name'" k-data-value-field="'ProgramId'" k-data-source="programIFormList | filter:{IsProgram: true}" k-cascade-from="'patient'"&gt;
                      &lt;/select&gt;
                  &lt;/div&gt;
                  &lt;div class="col-lg-2 col-md-4 col-sm-4 col-xs-4"&gt;
                      &lt;select kendo-drop-down-list k-data-text-field="'Name'" k-data-value-field="'ProgramId'" k-data-source="programIFormList | filter:{IsProgram: false}"  k-cascade-from="'patient'"&gt;
                      &lt;/select&gt;
