I have adapted it slightly for the codepen since the original has some prefilled data coming from an ASP-codeblock. But for the codepen demo I’ve prefilled only one reminder (as you must have atleast one). The current solution is in a working state, but then… plot twist. The software needs to support IE down to 7. And when loading it in IE, nothing works. Not even the table design :/.
Some more metadata:
There is a maximum of 5 reminders.
You can only delete the last reminder at every point in time.
You can not delete the first reminder (since it’s compulsory).
