Where to translate add close buttons for select field your variant feature?

Giorgi625 it looks like that it is loaded from some javascript function which I am not able to find.

It's located in Cobalt library folder: main.js
See line 540 ++

The text constants are "Add" and "Close".
You can create language overrides for them as usual.
Although they have no specific Cobalt naming convention, and they are camel-case.
On save... your overrides turn UPPERCASE automatically. But they will work.

BTW, there is also a constant for the "enter value" alert message: CENTERVAL

Thanks pepperstreet
