How to set a URL for the top level of a Structure section? I have entries in a structure section. I'd like the users to view the list of entries without the entries themselves being assigned URLs.

How can I set a URL for the top level of a Structure section without enabling "Entry URL Format"?
If I understand what you're asking—it sounds like you can just disable URLs for that section, and create a template that will get loaded at the URL you want.

For example, if you had a Section called “Plants,” and you wanted to list all plants at mywebsite.com/plants, you could just create craft/templates/plants.twig:

{% set plants = craft.entries({ section: 'plants', limit: null }).find %}

&lt;ul&gt;
  {% for plant in plants %}
    &lt;li&gt;{{ plant.title }}&lt;/li&gt;
  {% endear %}
&lt;/ul&gt;


If you need to edit anything on that page, you'll need to create another entry (probably a Single) to manage that content.
