My category hierarchy is as follows:

Top
-Parent 1
–Child 1
–Child 2
–Child 3
-Parent 2
–Child 4
–Child 5
–Child 6

How can I modify my template to only show the children of a single parent?

For example, I want to print out Child 1, Child 2, Child 3 on a single line, and then later in the template print out Child 4, Child 5, Child 6 on a separate line.

A bit of an update, I’ve got the following code working, which shows the categories that are assigned to the individual:

<?php
echo "<ul>";
foreach ( $entry->getCategory() as $category ) {
	if ($category->parent == '6') echo "<li>". $category->name . "</li>";
}
echo "</ul>";
?>

Is there some way to get all of the children of a parent category? And then highlight the ones that are assigned to an individual?

Example (if the individual is assigned child categories 2 and 3 but not 1 and 4):

o Child 1
x Child 2
x Child 3
o Child 4

Basically, trying to show all the child categories and “check off” the ones that have been assigned.

@ David

This is a bit complex…

Probably the closest code example I can give is this:
https://github.com/Connections-Business-Directory/Connections/blob/0.8.14/includes/class.metabox-entry.php#L388

That the code that creates the checklist in the admin.

The related function being used is here:
https://github.com/Connections-Business-Directory/Connections/blob/0.8.14/includes/class.form.php#L264

And that calls a couple recursive functions for transversing the category tree and output the list.

It is come pretty old code that is going to be rewritten because it can be done better … but this should at least give you the idea of how to put this together. Hope it helps!
