Description
Sometimes, if you are using the ListPages module for data presentation, you may list duplicate results. In such cases, you can use this special add-on to remove all duplicated instances, and place them in a list.
Code
Create an inc:iframe-append page, and on it, copy and paste the following code:
{$no-results}
[[embed]]
<iframe src="about:blank" style="display: none; [!----]"></iframe>[[/embed]]
You would then use a ListPages module to compile the list that may have duplicate results:
[[module ListPages perPage="250" limit="250" separate="false" appendLine="[[include inc:iframe-append |no-results=Sorry! There appears to be no results matching your specified criteria...]]"]]
[[embed]]<iframe frameborder="0" scrolling="auto" style="width: 100%; height: 300px;" src="http://snippets.wdfiles.com/local--code/code:remove-duplicate-results[!----]#ITEM[!--
[[/module]]
If you would like to use your own custom CSS for this module, just prepend ##CSS-URL to the [!----] code, like so:
[[module ListPages perPage="250" limit="250" separate="false" appendLine="[[include inc:iframe-append |no-results=Sorry! There appears to be no results matching your specified criteria...]]"]]
[[embed]]<iframe frameborder="0" scrolling="auto" style="width: 100%; height: 300px;" src="http://snippets.wdfiles.com/local--code/code:remove-duplicate-results##CSS-URL[!----]#ITEM[!--
[[/module]]
The CSS class used to control the items in the list is .unique-item
In action
This code would be useful if you want to list the most active users over the past 24 hours:
**Currently Active Users:**
[[module ListPages category="*" order="updated_at desc" date="last 1 day" perPage="250" limit="250" separate="false" appendLine="[[include inc:iframe-append |no-results=There appears to be no active users over the past 24 hours...]]"]]
[[embed]]<iframe frameborder="0" scrolling="auto" style="width: 100%; height: 125px;" src="http://snippets.wdfiles.com/local--code/code:remove-duplicate-results[!----]#%%created_by%%[!--
[[/module]]
Currently Active Users:

Well done, James.
Now it would be great if you could count the contributions per user and append (nn) to username, with a new class .count-item, for {display:none;} if not wanted.
