Embedding your ConvertKit forms into your Showit site is really simple.

First log into ConvertKit and select Landing Pages & Forms, then style your form and dial-in your settings.

Once your form is finished click the </> EMBED option to copy your form's embed code to add it to Showit.

Once you have your form embed code copied head over to Showit, select the canvas you want to add the form to, and choose the embed code option as shown below.

Then click inside the "custom code" box in the Properties Panel (right) once you've added the embed element to your canvas and paste your code into the box that pops up and click save.

That will do it! Your form will load in the widget container and you can resize it as needed.
