Answer 1

Where does the selection happen, are you fine with hard coding the IDs to use / skip in your code?

You have the child's term id in $child, just add

if(in_array($child, array(123, 456))) continue;

before

$term = get_term_by( 'id', $child, $taxonomy_name );

to skip over the categories 123 and 456, or use !in_array to only show those and skip the others. You can use a variable instead of array(123, 456) , of course.

Edit: turning this into a shortcode is pretty easy as well:

add_shortcode( "mycategoryprinter" , function($attributes) {
    $skipids = array();
    if(array_key_exists("skipids", $attributes)) {
        $skipids = preg_split("/\s*,\s*/", $attributes["skipids"]);
    }
    $term_id = $attributes["termid];
    $taxonomy_name = $attributes["taxonomy];

    // code goes here, change echo to return

});

Which you can then use with something like

[mycategoryprinter termid="1292" taxonomy="product_cat" skipids="123, 456"][/mycategoryprinter]
