Categorizing Posts in a Meteor Collection

Question

I have a Meteor Collection called Posts as shown below:

Posts = new Meteor.Collection('posts');

I want to categorize them by a field I call "genre" and have different genre posts appear in different tabs in my navigation bar. I've tried installing tags for meteor and creating multiple Collections, but those attempts have not been successful.

Does anyone know how I can categorize one Posts collection (if possible) into multiple feeds on different tabs and sort them by time created?

Actually this is pretty easy with meteor

You should first create and event handler like this if you don't know about event handlers or insert into collections take a look into insert method on Mongo.Collections and event handlers Meteor Events Handlers

This is how a Event handler look on MeteorJs

template.navbar.events({
  'click #button':function(){
    Posts.insert({genre:"Rock"})
   }
 })

or if you want to skip the event handler (just for testing purposes) create a folder named /Server with a file inside name testInsert.js with this code

so our path look like this /appName/server/testInsert.js

if (Posts.find().count() === 0) {
  Posts.insert({
    genre: 'Rock',
  });

  Posts.insert({
    title: 'Music',
  });

  Posts.insert({
    title: 'Art',
  });
}

Now we need to show the Posts Data on the Meteor template, so we need a Meteor Template.helpers

Template.navbars.helpers({
  showGenre:function(){
   return Posts.find();
  }
})

And this is how we call that helper on the Template,Meteor uses the spacebars engine on the templates.

If you wanna take a deep look into Spacebars take a look into this Understanding Spacebars

 <template name="navbars">
    {{#each showGenre}}
      <!-- navbar stuff go here -->
      {{genre}} <!-- here you are only calling genre field from Posts Collection -->
    {{/each}}
  </template>
