I am using angular UI-Router and bootstrap collapse panels to build a sidebar for a style guide. My sidebar as is "works" but I'm getting a
Error: Cannot transition to abstract state 'parent'
when clicking the child states. In my real solution there are many parents with child groupings and the parents truly are abstract (i.e. they don't represent a physical page or state). I know I can't link directly to the parent states, and I don't believe I am, I just need to set their ui-sref
in the parent panel so that I can get the parent to stay open by setting the ui-sref-active
attribute.
I have an example running on plunker:
code for reference:
angular.module('app', ['ui.router'])
.config(function($stateProvider, $urlRouterProvider){
$urlRouterProvider.otherwise("/");
$stateProvider
.state('home', {
url: "/",
templateUrl: "layout.html"
})
.state('parent', {
abstract: true,
url: '/parent',
templateUrl: "layout.html"
})
.state('parent.child', {
url: "/child",
templateUrl: "child.html"
})
});
layout.html
<div class="container-fluid">
<div class="row">
<div class="col-xs-3">
<a ui-sref="home">Home</a>
<div class="panel-group" id="sidebar">
<div class="panel panel-default">
<div class="panel-heading">
<h4 class="panel-title">
<a data-toggle="collapse" data-parent="#sidebar" data-target="#parent"
class="collapsed">Parent</a>
</h4>
</div>
<div id="parent" ui-sref="parent" class="panel-collapse collapse" ui-sref-active="in">
<div class="list-group">
<a ui-sref="parent.child" ui-sref-active="active" class="list-group-item">Child</a>
</div>
</div>
</div>
</div>
</div>
<div class="col-xs-9">
<div ui-view></div>
</div>
</div>

Reset to default 5Short Answer:
Just remove ui-sref="parent"
from your code. This particular ui-sref
attribute is not required in order for ui-sref-active
to work as you expect.
Long Answer:
ui-sref-active
works by finding all child elements with a ui-sref
and adding these elements to a states
array attached to the element. On $stateChangeSuccess
, each element loops through this array and if a state is found that matches the array, then the class is applied.
As an example:
<ul>
<li ui-sref-active="open">
<a ui-sref="app.home">Link</a>
<ul>
<li>
<a ui-sref="app.home.this"></a>
</li>
<li>
<a ui-sref="app.home.that"></a>
</li>
<li>
<a ui-sref="app.home.whatever"></a>
</li>
<li>
<a ui-sref="temp"></a>
</li>
</ul>
</li>
</ul>
In the above example, assume app
is an abstract. All 4 of those links will trigger the open
class on the parent element, as they are contained within. It doesn't matter that they are not all part of the app.home
structure.
