Available as a Pro feature, you can embed your form on your Editor X (formerly Wix) site. To add your form, you'll first need to add an 'Embed Widget' content block to your page.
Next, click 'Enter Code' to open the code editor.
Then copy your embed code and paste it into the code text area and click 'Update'.
Select the Embed Widget/iFrame block and open the sidebar settings panel. Adjust the Height or any other values to accommodate the full size of your form.
Finally, publish your page to see the form live on your site.
