Having an issue with collapsible feature when only one item is opened in AngularJS

I'm working on customizing a collapsible feature in my app. Instead of using the AngularJS UI Bootstrap accordion plugin, I opted to use transition.js and collapse.js from Bootstrap for a simpler design. My goal is to have 2 links next to each other with collapsing elements opening in a row below them.

Here's what my current code looks like:

<div class="logo" id="accordion">
      <a data-parent="#accordion" data-toggle="collapse" data-target="#login">
        Log In
      </a>

      <a data-parent="#accordion" data-toggle="collapse" data-target="#signup">
        Sign Up
      </a>

      <div id="signup" class="collapse">dfkñfkldsklñfdsñlkfd ñlkdflkfdñlfsdñl ksfdlkfdslñsfdñl kfdkfkldl fdksñlfdklfdñksfd

      <div id="login" class="collapse">blablabla</div>

</div>

The collapsing effect is working well, although I'm still trying to achieve the "only one item opened at a time" behavior. Could there be a conflict with the AngularJS files causing this issue?

Answer №1

In order to manage the mutual exclusivity between two variables, loginCollapsed and signUpCollapsed, it is recommended to handle it in the controller by setting up a watch function:

// untested
$scope.$watch('loginCollapsed', function(val){
  signUpCollapsed = !loginCollapsed;
})

The angular-ui team has established some best practices for implementing an accordion that can open one or multiple bellows:

Implementation source: 

if ( closeOthers ) {
  angular.forEach(this.groups, function (group) {
    if ( group !== openGroup ) {
      group.isOpen = false;
    }
  });
}
