Unable to create a service from a template

[jeremystretch]

Deployment Type

Self-hosted

NetBox Version

v4.2.8

Python Version

3.10

Steps to Reproduce

1. Create a device with at least one interface.
2. Assign an IP address to an interface on the device.
3. Create a service template for e.g. TCP/443.
4. Click "add a service" under the device view. This will present the service creation form with the current device already selected.
5. Select the service template and IP address, then click "create."

Expected Behavior

The service should be created.

Observed Behavior

No action is taken. The form does not appear to be submitted.

It looks like the widget for the protocol field is rendered with the required attribute set, even though the field itself is not required. This appears to be a regression introduced by #18971, however we'll need to determine the proper fix as we definitely want to include the required attribute on <select> widgets where applicable.

As a workaround, you can select a protocol under the "Custom" tab. This will be ignored when a template is selected, and will allow the form to be submitted.
