Thank you, that worked brilliantly. Merry Christmas!

Thanks for the reply. Unfortunately I have discovered that my host (1and1) does not enable theme or plugin editing without altering wp-config.php. I’m inexperienced with wordpress and not confident in changing this, so for the meantime I won’t be able to implement your advice.
Again, your reply is much appreciated.

Is there any way to achieve this through coding?

Perhaps a collapsable menu?

That seems to have resolved the issue. Thank you!

Is the problem perhaps that I’m using WordPress 4.6.1?
