Style of WooCommerce Multi Currency in front end

Hi,

To show the multicurrency on my website I disabled the sidebar and put the shortcode into the plugin “menu shortcode” to be visible on the secondary menu : [woo_multi_currency]
It’s very functional, thanks a lot for the work.

However their is 2 problems :
1/ How to change the design to this ? It looks very bad on the front end right now. (photo with the message)
2/ How to disable the special currency menu on product pages ? It looks very bad too.
Thanks in advance !
