Currently there are two blocks.
Simple Hide block is a simple, easy and useful block that places a title and an open icon.
The following paragraph or content is hidden until the user clicks the open icon.
It uses an open icon (+) to show the paragraph content following the title.
A close icon appears (-). Then, you can use a close icon to hide the paragraph content following the title.
Simple Toggle is the same block without icons.
Just click on the first paragraph to toggle the second paragraph.
