Enable language specific printing of roadmaps

[joycarpediem]

Requirements The roadmap created by members is mostly in german but also sometimes in english . When we download the roadmap as a PDF, all the text except the user entered text is in English . So if the user entered text is in German, we get a combination of German and English which effects the readability of the documents . Since these roadmaps will be published publicly, it is important that they are more readable . So they contain a singular language and that is based on the language that the member is using for setting up the roadmap

Implementation

• We will need to store the "language" of the roadmap
• While printing we will read this language and render the system texts based on the language of the roadmap . So if the language is set as German, the system text like the category names ( traceability etc) are all in German . Same goes for English
• We now have a language selector for the entire site but we do not store that as part of the submission

Design

• Add a language selector dropdown next to the organisation called "Roadmap Language"
• The selection will determine the translation for the roadmap questionnaire
• Save this value on submission
• While printing read this values from the questionnaire .
• How will we get the texts that are not part of the questionnaire like submission date etc ?

Print
