Adding a language parameter in f7SmartSelector

[dtamien]

Hello !

Thank you very much for providing this package. I'm using it to develop a web app in order to help people in need.

I'd like to be able to change "Search" for "Rechercher" (French).

Could you please let us do that by adding a parameter such as languagein the f7SmartSelector options? It would be great If we could aslo do that for the "Close" text. I'd set it to "Fermer".

All the language options can be controlled from the framework7 documentation: https://framework7.io/docs/smart-select#smart-select-parameters. This could give:

f7SmartSelect(
         inputId = "variable",
         label = "Selectioner une variable:",
         selected = "drat",
         choices = colnames(mtcars)[-1],
         openIn = "popup",
         popupCloseLinkText = "Fermer",
         searchbarPlaceholder = "Chercher"
       )

Unfortunately, searchbarPlaceholder would have to be revisited. It is initialised here which basically overwrites any user change:

config <- dropNulls(list(openIn = type, searchbar = searchbar, 
        searchbarPlaceholder = "Search", virtualList = virtualList, 
        ...))
