Lawstudio is multi languages, if you create your site from the Lawstudio Quickstart package, you just have to avoid the following steps:
1. Install in new idima: go to Extensions >> Languages >> Click in Install Languages Button.
2. Publish the content language: go to Extensions >> Languages >> Content Languages >> And publish the content language just created with the installation of your language. If it was not created, you can create one using the Button New and using the English language as an example.
3. Create a new menu with the name of your language (EX: Menu English (en-GB)); All menu items for this language are stored in this menu.
4. Create the main menu item for this language; for this, in the menu item creation screen, in the sidebar, in default page select Yes, in Language select recent installed language.
If you have installed the template on an existing site or do not start with the quickstart, you also have to follow the steps below

6. Go to Extensions >> Modules >> New >> select Language Switcher >> Add a Title in position field select languageswitcherload and save your module.
