Get the first 3 elements of the main collection in an underscore pattern

{{_.each(model, function(item) { }}
<h5 style="color:#F30;">{{=item.name}}</h5> 
        {{for  (i = 0; i < item.subcollection.length; i++) {  }}  
               <li><a>{{=item.subcollection[i].split('#')[0]}}</a></li>
         {{ } }} 
{{ });}}

I have an underscore pattern for rendering a collection of base models that contains a subcollection inside. But I only need to display the first 3 collections when rendering. ny help

I'm not sure what you are trying to do, but if you only want the first three to be done, set the counter to 3 instead of collection.length

 {{for(j=0;j<3;j++){ }}
<h5 style="color:#F30;">{{=model[j].name}}</h5> 
        {{for  (i = 0; i < model[j].subcollection.length; i++) {  }}  
               <li><a>{{=model[j].subcollection[i].split('#')[0]}}</a></li>
         {{ } }} 
{{ } }}


Note: Make sure the length is at least 3.
