How to add a button for show or hide transcripts?

Hi Mai,

You can hide the transcript by default under the button at:

WP Admin dashboard -> Settings -> FV Player Pro -> scroll down to find Video transcript field -> click on the Hidden by default option.
(as you can see in the screenshot)

Now your transcripts will be automatically hidden under a button on all of your videos.

If you want to find more information about Interactive Transcript you can check our Video Interactive Transcript documentation.

Thanks for using our player,

Juraj
