Django ForeignKey replace dropdown with Popup

Question

A very stupid question, but I just could not figure out how to it simple.

In my model (says Measurements) I have a ForeignKey to link the device that we want to add Measurements (device_link = models.ForeignKey(Device, null=True, blank=True,on_delete=models.PROTECT))

I made a Form to create a new Measurements and globally it works well and straightforward.

But to choose the Device, Django use a select field via Dropdown menu. So if we have a lot of devices it could be very difficult to choose the desired device.

So, I'd like to replace dropdown select menu with a link that open popup window with a list of devices. User choose the device, click and then get back to the form inserting selected device.

Sounds simple, but I could not find how to do it in Django.

What I have tried already :

1. django-addanother

It works very well and do almost that I want... but not exactly, it allow to Add new Device instead of choose.

2. django-autocomplete-light

Seems to be very close to that I want, but I could not find any popup example.

3. django-select2

I could not understand if it could do that I want. I tried to make a little test and could not found out how to use it.

So... Are there any way to do it in simple and light way ?

I found a similar question here : Django admin, override dropdown with selection from popup window

But in my case I'm not in Django Admin situation, but just my simple app.
