I will attach it here, can you in return attach it to the very first post and write that is s a re-write of the original etc. Because I think there is a problem with the original config.php file,
Frank.
Here the corrected cssplay-flyoutrev02.php file. Rename attached file from *.txt to *.php and upload to the assest/snippets/wayfinder/configs folder. Simply add the following call in your template in the place you want.
[!Wayfinder? &config=`cssplay-flyoutrev02`!]
And alter the assets/snippets/wayfinder/examples/cssplay/flyout_revisited.css file to suite your needs.
