Embedding your ConvertKit forms into your Showit site is simple.
Create Your ConvertKit Form
First log into ConvertKit and select Landing Pages & Forms, then style your form and dial-in your settings.
Embed Your ConvertKit Form in Showit
Once your form is finished click the </> EMBED option to copy your form's embed code to add it to Showit.
Once you have the embed code for your form copied, head over to the Showit Design App, select the canvas you want to add the form to, click on the Element Icon in the Bottom Toolbar, and choose the embed code option as shown below.
Click on the newly added embed code box that appears, and paste the code from ConvertKit into the Custom Code box in the right side Properties Panel and choose to Save.
That will do it! Your form will load in the widget container and you can resize it as needed.
