                        <!--xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx -->
                        <div class="editor span8" id="RECORD">
                            <button type="button" class="btn btn-mini btn-toggle">
                                <i class="icon-pencil"></i>

                </ul>
            </div>

my question is how not to render the form at all, not to hide it with ng-show or ng-if

Answer 1

ng-switch is designed to do precisely this. It actually removes and inserts items into the DOM based on the condition.

Answer 2

I usually use ui-if from angular-ui for this.
