I am trying to create an app where users can send bulk messages. One of the features I am trying to implement is the ability for users to upload a CSV file. This allows them to create their own headers, as shown below:
Then, in my dropdown element, I will reference the headers from the CSV, giving users choices like [First Name], [Last Name], [Number], and [Order].
In the message input box, users can create a message like “Hello [First Name], your [Order] order is due today.”
Is there any plugin I can use? I have already implemented a similar feature, but the problem is that I am saving it in the database, and the variables are static, so they depend on the columns in my database.
