Runway category loop

Does anyone know if there a way of looping through specific categories in Runway?

For example, I've created the following categories in 'Set A':

Category A
  Sub Cat 1 of A
  Sub Cat 2 of A
Category B
Category C

perch_categories(); will obviously loop through ALL categories in a nice nested list. Is there a way of only displaying/selecting level 1 categories - so return Category A, B and C, but exclude Sub Cats of A?

You may be able to test catParentID - it should be 0 if it's a top level cat.

<perch:if id="catParentID" match="eq" value="0">
   ... this is a top level category ...
</perch:if>

Works perfectly. That's great, thanks.

Can I use the same approach for showing only Sub Cats? So, if I was on Category A page, only loop through Sub Cats of A, excluding Category B and C?

You should be able to match the path. Set the path of the parent you want to select from the page:

PerchSystem::set_var('selectedCat', 'foo/category-a');  // or use perch_get('cat') or whatever

Then in your template:

<perch:if id="catPath" match="contains" value="{selectedCat}">

</perch:if>
