Multilingual Support - I need to make the website multilingual. Part of it is in place, but I'd need your help to make sure that everything is setup properly 2. Forms - I have two forms 2A. Account Opening : [login to view URL] What's missing: - Functioning + Add x Remove function for certain dropdowns - Review section that allows you to edit the forms - Sending function sends JSON data to somewhere and returns an application number 2B. Mortgage Application : [login to view URL] What's missing: - Review section that allows you to edit the forms - Sending function sends JSON data to somewhere and returns an application number 3.
