Try to work with components
You can use: categories-and-latest-topics
In this mode, there is a connection and categories and recent topics.
<script type='text/x-handlebars' data-template-name='components/categories-and-latest-topics'>
<div class='column categories'>
{{categories-only categories=categories}}
</div>
<div class='column'>
{{categories-topic-list topics=topics filter="latest" class="latest-topic-list"}}
</div>
</script>
Next, you override: categories-only
<script type='text/x-handlebars' data-template-name='components/categories-only'>
The contents of the file...
</script>
Perhaps from this file it is necessary to move the box with the categories, or to do simply to change the css.
Options think very many.
