Rear port selection widget not working properly when creating Front Port templates

[shatt79]

NetBox version

v3.5.2

Python version

3.8

Steps to Reproduce

1. Go to device-types and select a device with multiple rear ports
2. Add multiple front ports
3. Unable to select a range of rear ports to associate with the multiple front ports.

Expected Behavior

Behavior should be like when adding front ports to an already existing device. You should be able to select a range of rear ports when adding multiple front ports.

When modifying an existing device, the process works properly (fixed in 3.5.2).

Observed Behavior

You can only select one port at a time rather than a range. When creating or modifying a device-type like a patch panel with hundreds of ports, this slows down the process.

Hello,

This is a multi-select box and I am still able to select multiple ports, you just have to select them one at a time, but multiple ports can be entered in the dialog. Are you seeing different behaviour?

@DanSheps - It's supposed to be a selection input like this:

Selecting tens of ports one by one is terrible UX. I think it was just missed in this issue as it wasn't specified that it applied to device types as well.

It looks like it might be missing:

    widget=forms.SelectMultiple(attrs={'size': 6})
