user 1 and user 2 can create there own choices and their choice can only been seen by themselves
how can I do this,I’ve tried several method but always failed finally.

In the Select field, you can apply Role and User Permissions. Perhaps you can try Custom Script. Here is the example.

User and Role Permission can only be applied on the link fields, like a Customer is a link field in the Quotation. With Role Permissions, you can specify which Customers will be visible to the User while creating transactions.
