I am currently developing a story map and I wonder, instead of putting a lengthy text on a single entry of the side panel (Side Accordion), can we add something like a "read more" button (or link) so once the reader click the link the rest of the text can show up within the entry, without adding a separate URL link or directing the reader to a separate entry?
I ask this because as far as I can tell, all built-in options of creating link as to do it "externally" (like an separate URL or separate section), but not within the same entry (like a "read more" link I try to create).
It seems some kinds of API or SDK is needed to make it work. So if you have suggestions, please kindly provide a step-by-step procedure for me to follow since I am a novice on scripts or codes (if not an outright phobia!). Greatly appreciated for any input and many thanks!
