BackboneJS Display multiple collections in one <ul>-Element - backbone.js

Question

I would like to know if it's possible to diplay multiple collections inside one <ul>-element?
for example when I have multiple views, in each view I have a collection like this:
Collection = Backbone.Collection.extend({
url: function() {
return '/path/to/JSON/file';
}
});
Now I want to display all Collections inside the same <ul>-element so that in my frontend it would give me the output
<ul>
<li>Data from Collection 1</li>
<li>Data from Collection 1</li>
<li>Data from Collection 2</li>
<li>Data from Collection 2</li>
<li>Data from Collection 3</li>
<li>Data from Collection 3</li>
</ul>
Is that possible? If yes then how?
Thanks in advance...
[EDIT]
Ok, so in my mainView I have:
Artist.View = Backbone.View.extend({
template: 'artistchannel',
beforeRender: function() {
var artistinstagramCollection = new ArtistInstagram.ArtistInstagramCollection();
artistinstagramCollection.artist_id = this.artist_id;
this.insertView('.socialMedia', new ArtistInstagram.View({collection:artistinstagramCollection}));
artistinstagramCollection.fetch();
var artisttwitterCollection = new ArtistTwitter.ArtistTwitterCollection();
artisttwitterCollection.artist_id = this.artist_id;
this.insertView('.socialMedia', new ArtistTwitter.View({collection: artisttwitterCollection}));
artisttwitterCollection.fetch();
var artistfacebookCollection = new ArtistFacebook.ArtistFacebookCollection();
artistfacebookCollection.artist_id = this.artist_id;
this.insertView('.socialMedia', new ArtistFacebook.View({collection: artistfacebookCollection}));
artistfacebookCollection.fetch();
Like mentioned before, each Collection is bound to its own view:
function (App, Backbone) {
var ArtistInstagram = App.module();
ArtistInstagram.View = Backbone.View.extend({
tagName: 'li',
template: 'instagram',
initialize: function() {
this.listenTo(this.collection, 'all', this.render)
},
serialize: function() {
return this.collection ? this.collection.toJSON() : [];
}
});
ArtistInstagram.ArtistInstagramCollection = Backbone.Collection.extend({
url: function() {
return '/myproject/index.php/api/social_feeds/instagram/' + this.artist_id;
}
});
return ArtistInstagram;
}
The same above goes for Twitter and Facebook. So I have 3 modules.
Then in the template artistchannel there is a section where I have:
<div class="socialMediaDiv">
<ul class="socialMedia"></ul>
</div>
And my HandlebarsJS-HTML template looks like:
{{#each this}}
<li>
<img src="{{title}}" />
<section class="ip">
<p>{{description}}</p>
<h3>
<time class="timeago" datetime="{{pubDate}}"></time>
{{type}}
</h3>
</section>
</li>
{{/each}}
When I do it like this it generates 3 <li>-elements, so the structure is like:
<ul>
<li>
<li>some results from collection 1</li>
<li>...</li>
<li>...</li>
<li>...</li>
</li>
<li>
<li>some results from collection 2</li>
<li>...</li>
<li>...</li>
<li>...</li>
</li>
<li>
<li>some results from collection 3</li>
<li>...</li>
<li>...</li>
<li>...</li>
</li>
</ul>
What am I doing wrong??
By the way, I'm using backbone's layoutmanager

It's certainly possible. When you render the collection view, just append to the container element (el or $el) instead of replacing its html.
