Changing js files text

Hello,

I'm using a zoho template for zohosites but I wish to change the language that it shows as a menu collapses in mobile version, the text show is "more" i want to show a + signal or whatsoever anyone that don't know english will understand.

I've downloaded the site to find out what was going on and found out that this is in the navigation.js file, but I cant't change it online or send a version with the text in a different language.

I would also like to request a way to make the templates in the language you wish for the stuff that are written, that sure would be a major improvement for the service. Also, if I could have 2 versions of my site one in English and other in my native language that sure would benefits in cases like mine. Just by the click of a button.
