How to bind a Controller's method in each of the item in ng-repeat?

<div uib-accordion-group class="panel-default" template-url="group-template.html" ng-repeat="item in myCtrl.Data">
</div>
Look at the above code snippet. I want to bind a method like myCtrl.update() in each item in the ng-repeat. So that later in the directive's scope I can invoke the method like item.update().

You can use ng-bind for that purpose.
<div uib-accordion-group class="panel-default" template-url="group-template.html" ng-repeat="item in myCtrl.Data">
<span ng-bind="yourMethod(item.Data)"></span>
</div>
Hope this will be helpful.

You can bind it as you do binding outside ng-repeat.
<div uib-accordion-group class="panel-default" template-url="group-template.html" ng-repeat="item in myCtrl.Data">
<button ng-click="myCtrl.update()"></button>
</div>

NG directives not working inside a ng-repeat that is inside another ng-repeat

So I have a ng-repeat that's inside another ng-repeat. I tried to use ng-class ng-hide and ng-show but it's not working in the child ng-repeat. It does however work inside the parent. For example:
<div class="product" ng-repeat="item in category.products">
<h2 class="product-name">{{item.name}}</h2>
<ul class="product-variety">
<li ng-repeat="variation in item.variations" class="{{variation.name}}" ng-hide="true">{{variation.name}}</li>
</ul>
</div>
The li with ng-hide does not work. How do i make it work?

Angular JS - ng-repeat and loop conditions

Hey i have this piece of code:
<div ng-repeat="i in values">
{{i}}
</div>
It works but i would like to put extra conditions inside the loop something like:
<div ng-repeat="i in values">
{{i}}
if(i !== 0){
<div></div>
}
</div>
How can i achieve this?

Use ng-if (or ng-show):
<div ng-repeat="i in values">
<div ng-if="i !== 0"></div>
</div>
Attached to the element, this will decide whether to display it or not.
Documentation for ng-if can be found here.
However, if you want to only do something if you are looping the first or last item, you can use $first and $last properties of ng-repeat as well. These are documented with ng-repeat. And can be used like this:
<div ng-repeat="i in values">
<div ng-if="$first"></div>
</div>

Use the ng-if statement
<div ng-repeat="i in values">
{{i}}
<div ng-if="i !== 0"></div>
</div>

AngularJS : Appending the same structure on the click of each item

My index.html page is like following:
<div id="sidepanel" ng-controller="myCtrl">
<ul class="drop-down">
<li ng-repeat="item in items">
{{item.name}}
</li>
</ul>
</div>
<div id="mainpanel" ng-controller="listCtrl">
<div ng-view></div>
</div>
For this ng-view I have record-list.html to show all the records which is like following:
<div class="container">
<ul class="design">
<li id="{{record.name}}" ng-repeat="record in records">
<div>......</div>
</li>
</ul>
</div>
Now i want to add the same structure (as like each record) append on the click of each item of the side panel.
what is the logic for that ?
My recent UI Looks like this & i want to add the same structure on each click which should be append the existing structure.
Please Help.Thanks.

It sounds like perhaps each "record" has a set of children "records." If this is the case, I would recommend using angular's ng-switch directive to conditionally display the correct (or no) set of sub-records on the side.

Access index of the parent ng-repeat from child ng-repeat

I want to use the index of the parent list (foos) as an argument to a function call in the child list (foos.bars).
I found a post where someone recommends using $parent.$index, but $index is not a property of $parent.
How can I access the index of the parent ng-repeat?
<div ng-repeat="f in foos">
<div>
<div ng-repeat="b in foos.bars">
<a ng-click="addSomething($parent.$index)">Add Something</a>
</div>
</div>
</div>

My example code was correct and the issue was something else in my actual code. Still, I know it was difficult to find examples of this so I'm answering it in case someone else is looking.
<div ng-repeat="f in foos">
<div>
<div ng-repeat="b in foos.bars">
<a ng-click="addSomething($parent.$index)">Add Something</a>
</div>
</div>
</div>

According to ng-repeat docs http://docs.angularjs.org/api/ng.directive:ngRepeat, you can store the key or array index in the variable of your choice. (indexVar, valueVar) in values
so you can write
<div ng-repeat="(fIndex, f) in foos">
<div>
<div ng-repeat="b in foos.bars">
<a ng-click="addSomething(fIndex)">Add Something</a>
</div>
</div>
</div>
One level up is still quite clean with $parent.$index but several parents up, things can get messy.
Note: $index will continue to be defined at each scope, it is not replaced by fIndex.

Take a look at my answer to a similar question.
By aliasing $index we do not have to write crazy stuff like $parent.$parent.$index.
Way more elegant solution whan $parent.$index is using ng-init:
<ul ng-repeat="section in sections" ng-init="sectionIndex = $index">
<li class="section_title {{section.active}}" >
{{section.name}}
</li>
<ul>
<li class="tutorial_title {{tutorial.active}}" ng-click="loadFromMenu(sectionIndex)" ng-repeat="tutorial in section.tutorials">
{{tutorial.name}}
</li>
</ul>
</ul>

You can also get control of grand parent index by the following code
$parent.$parent.$index

You can simply use use $parent.$index .where parent will represent object of parent repeating object .

$parent doesn't work if there are multiple parents. instead of that we can define a parent index variable in init and use it
<div data-ng-init="parentIndex = $index" ng-repeat="f in foos">
<div>
<div data-ng-init="childIndex = $index" ng-repeat="b in foos.bars">
<a ng-click="addSomething(parentIndex)">Add Something</a>
</div>
</div>
</div>
