  Hello,

   How can I set up the combobox to not select any item at all when it's initialized? I tried setting the selectedIndex=-1 but it didn't worked. Also tried to set the selectedItem = null and put isRequired to false, but still no results. I`m using Angular 2.
  

  Thanks,
  
  Cosmin

  Hello Cosmin,
  
  Please set currentItem to null of CollectionView instance. Please use the following code snippet for the same:

  // this.data=> CollectionView instance
  this.data.currentItem=null;
  

  Thanks,

  Hello team,

  I recently upgraded wijmo for our AngularJS application from version 5.20161.154 to 5.20172.334.
  
  After this i see that all the wijmo dropdowns throughout the application that were earlier initializing with no default values selected are now appearing with the first item in dropdown selected by default.

  I see there is a solution provide above but i do not want to go into each and every controller and set this code for each dropdown in the whole app. Is there a generic way to do this since it was working as desired with older version. Not sure what changed with the upgrade in order to change this behavior.

  thanks,
  
  Liju

  Hi Liju,
  
  You may bind all the ComboBox with collectionView. And set teh CurrentItem to null. Please refer to the following fiddle for the same:
