I am trying to add multiple values for a user , can someone help me with this ? Currently, user is supposed to select a value or multiple values example - a User may follow one topic or multiple topic. Whenever a user selects a value corresponding row value is updated but it overrides the previous value. Can anyone help me what I should be doing so that multiple values can be added for the same user. Any example video would be useful for this.
Similarly, File Picker, once the file is selected , how to retrieve and view it. Any limitations on file formats can be uploaded/viewed ? Any example video would be useful for this.
