Thank your for posting your question here!
This is a really great question, and I’ve searched through the forum and have found a topic posted with the information you are looking for: How to filter out options in a multiple choice list based on user role?
As Julian mentions in the thread shared above, I suggest to avoid using JS and let the database do what it does best.
To achieve this, you can set the Multiple Choice field up as a Connection field instead and have field(s) in the “looked up” table which you can then use to filter the dropdown on Form view(s) as you need. So, you would need to create a new table that has the three options of “In Progress”, “Completed”, and “Awaiting Information” that you would connect to the table that the Form view(s) in your Live App would be creating records for.
Sounds confusing? I have created a simple app to display this setup by sharing a few screenshots in case having a visual reference helps.
Example Status field input setting in a Form view:
Then, for your Service Staff members, you could create a page that only gives permission to access to Service Staff user role Accounts that will allow them to edit the records’ Status value.
For the Service Staff scenario of them editing, this can be done a few other ways, such as, having a view on page to edit a Ticket record that is hidden for users that have the “Library Staff” user role by adding a Page Rule.
I hope this helps and guides you in the right direction. However, if you are unsure about how to accomplish your goal after reading this, please reach out to our support team! They would be very happy to help you create this workflow and would be able to take a look at your current app and the way that you have already setup your tables, user roles, pages, etc.
