To add a waitlist widget to your Wix project, please follow the guide below.
Go to your Wix website editor.
Click on "Add Element".
Click on "Embed Code", and then "Embed HTML".
Enter the URL for your Hosted Waitlist. You can find it by logging into your Waitlist Dashboard, navigating into the Widget Builder for your Waitlist, and clicking on "Show Hosted Page". (For step-by-step guidance for finding the URL, see the first two steps in the iframe guide.)
Drag the element to an appropriate spot in the Wix builder, and size it appropriately.
Hit Publish. Congratulations, you're done!
In step 3, when you select HTML element, it is also possible to select a Custom Element if you are on a paid Wix plan. Custom Elements can pull in arbitrary code that is uploaded to an external file. You may be able to upload the 3-line Waitlist HTML Snippet as an external file, and then paste that link into the Custom Element configuration. This may yield a visually better result than the HTML element, but we haven't tested it.
