How to Restrict Dropdown Values Based on User Access in ThingWorx?

Hi everyone,

I'm working on a project in ThingWorx where users (e.g., customers) should only be able to see and interact with their own data. Here's the scenario:

🔧 Past Setup:

• I have a configuration table that includes a field subUnitMapping, which links customers to their specific datasets.

• When a new customer accesses the application for the first time via mobile, a dataset is dynamically created and the appropriate subUnitMapping is assigned to both the dataset and its Thing for permission control.

• In the mashup, users select their line from a dropdown, press a button, and are navigated to their respective mashup/data.

🧩 Current Setup Challenge (new project):

        I have datasets for different customer and customers land to dropdown page where they choose their name from dropdown and then enter to navigate to their own mashup. I mean i can make this with textfield that they have to write something in it and enter to come to mashup with their own dataset....

• In the dropdown list, all customer values are visible, which is a problem.

• If Customer A sees and selects Customer B’s line by mistake (or intentionally), they will be redirected to someone else’s mashup — which is a security  issue.

❓ My Goal:

I want each customer to only see their allowed dropdown value(e.g., only their dataset/lines) in the dropdown.

🧠 Any Ideas?

How can I:

• Restrict the dropdown options based on user access?

Appreciate any suggestions, best practices, or examples!

Thanks,
