This extension lets you create option description which could be shown as tooltip on product page.
Description could be multi lingual.
Extension is ocmod based , no core changes in files.
It works well with default opencart structure i.e default theme and no conflicting extensions
Found to work with journal 2.8 theme also .
It could be made compatible with other themes also without any price ,but that is not the compulsion for the developer.
This extension is made by shambhalnetworks which has many other beautiful extensions.
