            </label>
        </div>

    <div class="clearfix"></div>
<div class="padding">
<div class="item item-divider calm-bg" style="color:#ffffff">

<div class="list">
     <label class="item item-input item-select">

                <div ng-if="(!teamName)">
                    <select>
                        <option value="" disabled> Select your form</option>
                    </select>
                </div>
                <div ng-if="(teamName)">
                    <select ng-model="FormModel" ng-options="f.id as f.formname for f in forms | filter:{teamid:teamName}">
                        <option value="" disabled> Select your form </option>
                </div>
            </label>
        </div>
    </div>

    <div class="clearfix"></div>
    <div class="padding">
    <button ng-click="showToFillForm(FormModel)" class="button button-calm pull-right">Go!</button>
    </div>
