My apologies, Bill. I thought there were more details on that script.
The shortcode used is [toggle] and to end it use [/toggle]. You can also use title=”custom title” within the toggle start to set a custom text to display; e.g. [toggle title=”Click to show/hide spoiler”]The butler did it[/toggle]
It can’t be used to hide part of a paragraph.
You can use it multiple times within a post or page should you choose.
