we should use name value pair binding values into dropdown see the   code for more details    x000D   x000D  function myCtrl  scope    x000D        scope statusTaskList     x000D            name   Open   value   1     x000D            name   In Progress   value   2     x000D            name   Complete   value   3     x000D            name   Deleted   value   4     x000D         x000D       scope atcStatusTasks    scope statusTaskList 0      0 - gt  Open  x000D    x000D   lt select ng-model  atcStatusTasks  ng-options  s name for s in statusTaskList  gt  lt  select gt  x000D   x000D   x000D

This is an old question and you might have got the answer already    My plnkr explains on my approach to accomplish selecting a default dropdown value  Basically  I have a service which would return the dropdown values  hard coded to test   I was not able to select the value by default and almost spend a day and finally figured out that I should have set  scope proofGroupId    47   instead of  scope proofGroupId   47  in the script js file  It was my bad and I did not notice that I was setting an integer 47 instead of the string  47   I retained the plnkr as it is just in case if some one would like to see  Hopefully  this would help some one

When you use ng-options to populate a select list  it uses the entire object as the selected value  not just the single value you see in the select list  So in your case  you d need to set    scope object setDefault         id 600      name  def       or   scope object setDefault    scope selectItems 1     I also recommend just outputting the value of  scope object setDefault in your template to see what I m talking about getting selected    lt pre gt   object setDefault   lt  pre gt

Problem 1   The generated HTML you re getting is normal  Apparently it s a feature of Angular to be able to use any kind of object as value for a select  Angular does the mapping between the HTML option-value and the value in the ng-model  Also see Umur s comment in this question  How do I set the value property in AngularJS  39  ng-options   Problem 2    Make sure you re using the following ng-options    lt select ng-model  object item  ng-options  item id as item name for item in list    gt    And put this in your controller to select a default value   object item   4
