Adding the data attribute to make it easier to potentially modify the DOM

[ajotka]

Hi! First of all, thanks for your work. I use this plugin in almost every Laravel project!

I came across a case where I have to edit selected content with JS. The problem has come up when for one tab (for one language) several divs are generated at the same level, without indicating what language they are for. (screen containing DOM below) Due to the fact that I had no way to "catch" these divs, I thought about adding a data attribute (data-lang & data-langfor). You might like the idea :)
