I worked on hiding the disabled variable in the maintenances to appear in all dropdown. This required adjusting the javascript and controller for all modules. Specifically, I updated the function 'disabled' to check the status of the variable before displaying it in the dropdown. Additionally, I modified the controller to call the 'disabled' function whenever the dropdown list is invoked. Finally, I tested the changes to ensure that the disabled variable is no longer visible in the dropdown. This activity was completed successfully.
