Disable option in Change Task Template

[samadam]

I have a standard change proposal where I want users to create new change task templates. I am trying to restrict the values displayed in the drop down i.e. make them read only. How can I access change task values from template if I want to create a onload script?

Hi @samadam 

Did you check the standard change properties

Hi @samadam,

It's absolutely possible. The Change Task Templates are simply Catalog Items behind the scene so you change the UI form as you see fit including applying scripts.

To modify an existing template, perform the following steps:

1. Navigate to All > Change > Standard Change > All Templates.
2. Select the template you want to modify.
3. Once you've opened the template, navigate to the bottom of the form where you'll see a link to 'Modify Template'.

From here you can edit the template as you would a Catalog Item. (Right-click at the top of the form).

Based on your requirement it is here you can restrict the value or options available in the dropdown with an onLoad script for example.

I tried to create on load client script with  disableOption('template.change_task_type', 'processing'); but did not work. Is this the right way to do it?
