Embed options for Wix
Wix allows you to embed Calendly using its native "Embed a Site" option, which (depending on what site theme you're using) will look similar to this:
SETTING UP "EMBED A SITE" OPTION:
1. Open your Wix site and click the Add button. Select More, then Embed a Site.
2. Select "Enter Website Address," enter your Calendly URL, then Update. You may also want to adjust the width and height of the iframe your Calendly page will appear in (this is optional upon style preference).
