Hard to tell without a live demo, but it might be the return false… That selector is targeting list items, not anchor links. Clicking a list item doesn’t have any default action you would need to prevent, so it’s probably not needed.
thanks for your help. i had no chance to test it without the return false yet.
cuz it’s a business page i can’t get u a live demo but perhaps the code of my sidebar.php could make it all a lil bit clearer.
