@manking109,

I think you may have a problem with your siteID setting. Currently, you have it picking up the attribute called allonnews from the content bean. I don't think you meant to do that.

I would think it should probably be something more like this:

<cfscript>
  catBean = $.getBean('category').loadBy(name='Jessup, GA', siteID=$.event('siteid'));
  parentCatBean = $.getBean('category').loadBy(categoryid=catBean.getParentID(), siteID=$.event('siteid'));
</cfscript>

That said, once you have actually obtain a bean by which you can pull out a category's parentID that you want to display the children of, you should be able to invoke this method (assuming you've placed the dspNestedCategories() method in your contentRenderer.cfc) by passing in that parentID such as:

#$.dspNestedCategories(parentID='yourCategoryParentID')#

Excellent function! I modified the href attributes of the anchor elements to suit the URL structure of my project, which looks like /mynewsfeed/?categoryid=[categoryid]. These two lines got me there:

local.itemCategoryURL = variables.$.event('scriptName') & "?categoryid=" & local.item.getCategoryId();
local.kidCategoryURL = variables.$.event('scriptName') & "?categoryid=" & local.kid.getCategoryId();

... though I do prefer your URL structure and it's making me re-think my URLs!

This function (or something simliar) should be included in Mura core!
