Hello,
Thank you very much for choosing our theme and for contacting us.
1. You need to create two HTML blocks for each language. Navigate to WPML > String Translation > Choose the admin_text_woodmart_option from the dropdown and find the title and the content block http://prntscr.com/lx5qpz for all fields;
If you translate mega menu blocks of the menu:
– Create the translation of the HTML block http://prntscr.com/mqhred > Translate independently > update
– Enter the menu in the translated language (you need to have all the items translated and synchronized) > enter the menu item > and add the HTML block as you usually do
2. You can activate your license twice: one time for staging site and one for life. You will not have any problems with your live site.
3. You can use https://fontawesome.com/v4.7.0/icons/
Best Regards
