Expanding paragraphs

I’m having trouble with I want to use the expanding paragraph feature reached via the top menu pick for adding an element. I have installed the element on my page but the editing feature did not include a button so I cannot get this to function work (ideally I wanted a little + symbol ).

Working in Nothing

Site link Site feature not launched because I can’t create the feature.

What I’m trying to do
I have a 5 line summary of an item, I want to click a button (or the text) and see it expand to a paragraph, or open a new page (preferable in a new browser tab).

What I’ve tried so far. I have used the top menu pick to add this element to a page. The tooling allows me to edit / create the summary text, but doesn’t generate a button or any linkages to a new page / the extended paragraph text.

Extra context I want to use the feature in a long list of technical info, so the ability to replicate the structure for every item is promising and if it will allow me to simply update the page with the text for every article rather than re-creating it all by hand every time that would be great.

Ideally, the extended paragraph will go from 5 lines to 15, with a further button directing the reader to a full page (or create a linked additional page). However, I can’t even get it to work with a single expansion level. As I’m here, ideally, the full page would also self populate with a “back button”

Are you using the collapsible text element or the accordions element ?

any screenshots of the editor ?
