Habpanel Widget Items

Hello!
My Rollershutter Widget needs 3 items, f.e.:

config.blind_item: rs_wz_klein
config.lamellen_item: rs_wz_klein_lm
config.auto_item: rs_wz_klein_auto

at the moment i have to give the widget all three item-names, but basically the 1st item should be enough. “lamellen_item” and “auto.item” can be created from blind_item…

could anyone please give me a hint on how to do this?

<div ng-if="itemValue(config.auto_item)=='ON'">
     <button ng-style="{'color': '#0db9f0'}"  ng-click="sendCmd(config.auto_item, 'OFF')">
      <i class="glyphicon glyphicon-refresh" style="font-size:20px;"></i>
    </button>
</div>

to this

<div ng-if="itemValue(**config.blind_item+'_auto'**)=='ON'">
     <button ng-style="{'color': '#0db9f0'}"  ng-click="sendCmd(**config.blind_item+'_auto'**, 'OFF')"
      <i class="glyphicon glyphicon-refresh" style="font-size:20px;"></i>
    </button>
</div>
