You can hide an item with the following code.

<script>
//In the URL containing HOME.COM/CATEGORY1/SUBCATEGORY1, the item with the ID HIDE-CONTENT will be hidden.
if (window.location.href.indexOf("/CATEGORY1/SUBCATEGORY1") != -1)
{ document.getElementById('HIDE-CONTENT').style.display = 'none'; };
>
</script>

You can show any element on pages with specified URL layout with below code. It will be hidden everywhere else. Before doing this, make sure you add the style style=”display:none” to the element. Thus, content that is already hidden will only be visible on certain pages.
<script>
//In the URL containing HOME.COM/CATEGORY/SUBCATEGORY the item with the id SHOW-CONTENT will be displayed.
//Assuming you saved this item as hidden before.
if (window.location.href.indexOf("HOME.COM/CATEGORY/SUBCATEGORY") != -1)
{ document.getElementById('SHOW-CONTENT').style.display = 'inline-block'; };
</script>
