<md-content layout-padding>
<md-grid-list md-cols="6"
md-row-height-gt-md="1:1" md-row-height="4:3" md-gutter-gt-md="16px"
md-gutter-gt-sm="8px" md-gutter="4px">
<md-grid-tile
ng-repeat="room in floorDetails.roomDetails"
ng-style="{'background': '#f2f2f2'}"
md-colspan-gt-sm="3"
md-rowspan-gt-sm="2">
<div layout="row" layout-align="center center">
<b >Room1</b>
</div>
<div class='md-padding' layout="row" layout-wrap>
<md-card class="md-card" ng-repeat="bed in room.bedIds">
<md-card-content>
</md-card-content>
</md-card>
</div>
</div>
