Hey There,
Thanks for posting in! Regretfully, this particular customization request is outside the scope of our support as this is not related to an issue with the theme and instead has to do with your customization of it. As such, you will need to investigate this particular issue on your own or seek help from a developer should you not feel comfortable making these changes yourself. If you have any further questions about the theme, we are more than happy to provide you with assistance on these inquiries.
By the way, you may use accordion element. We can style it to have a transparent background and the accordion item can be shown or hidden once you click the title.
Thank you for your understanding.
