Here is my tree structure:

On the Some Event page I have a DataType to choose a category. I'm trying to use the MultiNode TreePicker and use the Xpath option to climb the tree from my current position to just show the categories.

• Events = eventMain
• Categories = eventCategories
• Category = eventCategory

I've tried every variation that I can think of but the only thing that works is:

$root//eventCategories

I don't want this because there are some customers that use this Events structure in multiple places on the site. I need the category picker to be context aware.

I've tried:

$parent//eventMain//eventCategories
$parent//eventMain/eventCategories
$parent/eventMain/eventCategories
$parent/$parent/$parent/eventCategories
$parent/$parent/$parent//eventCategories

But apparently you can't stack the placeholders?

Is there a solution to this that I'm not seeing?
