Re: Transparent Artboard not working

I have had the same issue. However, the drop down menu suddenly appeared when I scrolled down in the properties panel.

@sarar27324216 – Have you tried resetting preferences, changing workspaces, moving the panel etc?

The following JavaScript may provide a workaround:

}

1. Copy the code text to the clipboard
2. Open a new blank file in a plain-text editor (not in a word processor)
3. Paste the code in
4. Save as a plain text format file – .txt
5. Rename the saved file extension from .txt to .jsx
6. Install or browse to the .jsx file to run (see below)

Hi there,

Thanks for reaching out.

When you select the Artboard background color do you see the drop downs? What type of file are you working with?
