I enabled the showMoreDetails parameter to facilitate the “Show More” / “Show Less” link in my FAQ card. I’m unsure why selecting that link fails to load the full text? I see referencing to {{truncated}} in the component.js but unsure where these variables are defined.
I’ve found that this behavior comes up if you try to use the showMoreDetails feature on a Rich Text field. This, as far as I can tell, is not currently supported.
If you pull in the field as plain text instead (i.e., do not use the Rich Text formatter), if possible, the showMoreDetails functionality should work!
