Toolbars in Ionic 2


i tried more to make icon at the top of button but is doesn’t work?

<ion-segment-button value="puppies" icon-top>
    <ion-icon name="map"></ion-icon>

second what should id do if i want to make 2 toolbars like pic? after make 2 inside the header how the structure will be if i want “ALL”, show the app normally under the second toolbar control, and “FAVORITES” show isolated page, can i do this by routing or there is another shorter way for this?
