Hi there,
theres not one specifically for the Footer widgets, but you can change all widget titles ( this will apply to any widget areas ) by adding this PHP Snippet:
add_filter( 'generate_start_widget_title', 'widget_title_start_tag' );
function widget_title_start_tag()
{
return '<p>';
}
add_filter( 'generate_end_widget_title', 'widget_title_end_tag' );
function widget_title_end_tag()
{
return '</p>';
}
Alternatively you can NOT add a title and insert your own HTML block above the widget to add your own title.
