Enter your suggestions in details:
On https://nodejs.org/en/download, the irrelevant options for downloading Node.js are currently shown in the dropdowns as disabled items:
This creates ambiguity for new users who are not familiar with these technologies. E.g., Chocolatey being disabled for Linux could imply that it's supported but not endorsed by Node.js.
And I believe that AIX needs to be removed from this list:
Even though AIX is enabled for Node versions 6+, it seems that all installation options for it are disabled. The AIX option is disabled for Node versions below 6. So, there is no way to download Node.js on AIX with the recommended or community methods.
