Update the value of ng-show to false after redirection to the home page from the login page using AngularJS

I am new to angularjs and encountered a problem which required me to change the value of ng-show="false" to ng-show="true" when the user is redirected to the home page after successfully logging in!

This is what I am attempting to achieve:

.controller('loginCtrl', function ($scope, ..., showmenu)
{
      $scope.dropdown = showmenu.hide;
      ....
}
.factory('showmenu', function() {
  return {
      show : 'true',
      hide : 'false'
  }
})

index.html

<div class="btn-group" dropdown="" ng-show="false">
  <button type="button" class="btn btn-danger">Kyle Thomas</button>
  <button type="button" class="btn btn-danger dropdown-toggle">
    <span class="caret"></span> <span class="sr-only">Split
      button!</span>
  </button>
  <ul class="dropdown-menu" role="menu">
    <li><a href="#/profile">Profile</a></li>
    <li><a href="#/setting">Setting</a></li>
    <li><a href="#/help">Help</a></li>
    <li class="divider"></li>
    <li><a href="#/login">Logout</a></li>
  </ul>
</div>

This dropdown should be visible upon redirection to home.html!!

Thank you

Perhaps you're utilizing the ng-show attribute directly as false, causing the value to not update when the scope changes. Instead, try using $scope.dropdown within the ng-show directive.

<div class="btn-group" dropdown="" ng-show="dropdown">
  <button type="button" class="btn btn-danger">Kyle Thomas</button>
  <button type="button" class="btn btn-danger dropdown-toggle">
    <span class="caret"></span> <span class="sr-only">Split
      button!</span>
  </button>
  <ul class="dropdown-menu" role="menu">
    <li><a href="#/profile">Profile</a></li>
    <li><a href="#/setting">Setting</a></li>
    <li><a href="#/help">Help</a></li>
    <li class="divider"></li>
    <li><a href="#/login">Logout</a></li>
  </ul>
</div>

The behavior of the ng-show attribute is such that Angular automatically handles the visibility through the ng-hide directive.

If ng-show ="true", it displays the HTML content. If ng-show = "false", it hides the HTML content without needing to use ng-hide explicitly.

In your controller, initialize $scope.dropdown = false; initially to hide the HTML content. Then, upon a user logging into your app, change the value of $scope.dropdown = true; to display the HTML content.
