Click
Exit Mode
next to Lightbox Mode or click the dropdown menu in the upper left corner of the screen to return to editing to the previous page.To link a button element or URL text to the lightbox popup, click the link icon, choose the Lightbox option, and select the lightbox page with your Fillout form from the dropdown list.
Add custom code to a Wix website for embeds outside the iframe

If you have a premium Wix account and your site is on a custom domain, you can use Wix’s custom code feature to embed your form anywhere, without the limitations of the iframe embed.
From your Wix account dashboard, open the
Settings
menu from the left sidebar. Scroll to the bottom of the page and click Custom code.Paste a Fillout Popup, Slider, or Full screen embed code into the text box. Choose which pages should use the code snippet and select Body - start from the Place Code in: list. Click
Apply
and preview your site to confirm the changes.
