VisualSP is a robust support system that can support up to 9 different languages. Many of our help items already have content in multiple languages. VisualSP will serve the Help item in the correct language by matching the default browser language of the user.
However, when using inline help buttons, there isn't an option to put in multiple language versions of the text that goes on the button. There are ways to handle this, but you need to think through how you want the button to work.
Option 1: If there is a Microsoft button on the page, instead of making it a separate button that people would click on elsewhere, you can choose to cover-up the Microsoft button and make it go invisible. This is just a way to take over the Microsoft button itself.
By positioning the invisible button over the Microsoft button, the Microsoft button is still visible, but when you click it, the VisualSP help item will open in the correct language as identified from the browser.

Option 2: In cases where you don't want the button to be invisible and instead would like an icon that would show a help item in two different languages, you can do the following.
Create a Rich HTML help item with 2 links to the same help item. All you need to do is edit the link anchor tag of the second link and replace it with the translated version of your language of choice. Configure this as an inline help icon and you will in effect have a multi-lingual menu.

Option 3: Another option is to have 2 help items, one for each language, but have each one attached to a different element that only appears in each language.

Watch this video for a visual explanation of these 3 options.
