Args -> walker -> has_children doesn't show them ?

[papypom]

Not sure if it's tailpress related or wordpress, so as I'm starting here.

I'm following (loosely) the Github Blog video on youtube, so far, so good.

The github blog has small dropdown carets in its menu (small down arrows that indicate that there is a submenu). This is not covered in the video, but anyway, I'm trying to put them there. So I'm writing a custom walker to do so. This walker checks for children, as shown in the code snippet hereunder :

class LTM_Menu_Walker extends Walker_Nav_Menu {
	function end_el(&$output, $item, $depth=3, $args=array()) {
		if ($args->walker->has_children) {
			$output .= '<h1>TEST</h1></li>';
		}
	}
}

The problem I have is that the $args->walker->has_children is false even if there is children, so the if part is never shown (if I remove the if, it shows fine).

My menu looks like this :

So it should show for the l'ASBL tag.

I'm blocked - and as this is not an expected behavior, my question is : does anybody stumbled on the same issue ? Could there be some kind of side effects from the submenu functions that are added by Tailpress ?

Seems to be unrelated to TailPress, see: https://wordpress.stackexchange.com/a/199847

You could do the following based on the answer linked to above:

class LTM_Menu_Walker extends Walker_Nav_Menu
{
    public function end_el( &$output, $item, $depth = 0, $args = array() )
    {
        if (in_array('menu-item-has-children', $item->classes ?? [])) {
            $output .= '<h1>TEST</h1></li>';
        }
    }
}

I'm happy this has nothing to do with TailPress - and the solution you've provided works perfectly.
