Catalog description
From Online Business Wiki
Every catalogue has a description field into which you can place a description text to the HTML/CSS/JavaScript code
Go to eCommerce -> Catalogues -> select one one of the catalogues -> Show More Options, you'll get a description field into which you can enter your text or HTML.
You then need to go to Admin -> More Customization Options -> Online Shop Templates -> Individual Catalogue. This is where you need to insert {tag_description} into the template from Tag Insert drop down menu in order for the catalogue description field to be rendered in your online shop. You can equally go to the "Main Catalogue Layout" and add the {tag_description} to this layout.
Now, every time you access one of the catalogues, its description will be displayed, which can contain snippets of HTML, text, image(s), even flash that are related to that catalogue.
Hiding catalogue description for detailed product view
What you need to do is place your catalogue header inside the catalogue description and hide it. You need to wrap it into a dive with an ID e.g.
<div id="catdesc" style="display:none">{tag_description}</div>
Then you need to place a JavaScript inside a small product layout that will reveal that div upon the page load. e.g.
<script type="text/javascript">
document.getElementById('catdesc').style.display = "block";
</script>
