Shanj,
I wanted same functionality. Here is how I did it
Go to plugin editor
Editing sgr-nextpage-titles/sgr-nextpage-titles.php (active)
Approximately 80% of the way down you will see this:
if ( $options['toc-position'] === 'top' ) {
$enhanced_content = $toc . $enhanced_content;
}
elseif ( $options['toc-position'] === 'bottom' ) {
$enhanced_content .= $toc;
}
I commented that whole part out and replaced it with logic to just put the TOC above *and* below the content.
Please see what I replaced it with below:
/*if ( $options['toc-position'] === 'top' ) {
$enhanced_content = $toc . $enhanced_content;
}
elseif ( $options['toc-position'] === 'bottom' ) {
$enhanced_content .= $toc;
}*/
$enhanced_content = $toc . $enhanced_content . $toc ;
Hope this helps
