Don't work in the window quick product view

Hi zsimm,
Is that quick view window provided by a plugin?

No, provided by a theme.

Strange situation:

Dropdown work only with plugin WC Products Quick View! It is working when plugin is activated, although it uses a quick view of the theme.

If you disable this plugin, it also does not work Dropdown.

Radiobutton don’t work in both cases.

Do you get any errors?

Others there are no errors.
The site is available online store for acting.
