Wix
Wix runs pasted HTML inside its own sandbox frame, which changes two things.
Add Wix’s embed / custom code element to the page and paste:
<script src="https://rentx.al/embed.js" data-rentx-partner="your-partner-id"></script>Then:
- Set the element’s size yourself. Wix gives embeds a fixed box and does not
let the widget resize it, so make the box tall enough for the calendar to
open: about 460px for
bar, 640px forpanel. Too short and the calendar is cut off. - Publish before judging it. Embeds frequently do not run in the editor.
The iframe version is built for a fixed box like this one, and its published heights are the 460px and 640px above — but its search button does not work, so read that page before choosing it.
Wix also has a site-wide custom-code section intended for analytics tags. It is the wrong place for this: the widget has to sit in the page where you want it to appear.
