With 123FormBuilder, you can create a contact form for Blogger and many other types of forms. Here’s how you can embed these online forms on Blogger.
After you’ve created the form in your Form Editor and tweaked your form settings, go to the Publish → Platforms section. Here click on the tab named Blogger and copy the code generated for your form.
Then, log in to your Blogger account and click the New Post button.
Afterward, select the pencil icon to switch to HTML view and paste the code that you’ve copied from your 123FormBuilder account.
Preview, Publish and you’re good to go.
Use a contact form for Blogger to expand your reach. Have your visitors contact you via a contact form or more.
If you want to use a lightbox form, you cannot see how it interacts on the page in preview mode. You’ll need to publish the page first.
Note: There’s a slight difference between Blogger and Blogspot. You use Blogger to create your blogs and blog posts, while Blogspot is the service that hosts them. Each blog is a subdomain on Blogspot (e.g. http://www.123blog.blogspot.com). So whether you refer to your blog as being from Blogger or Blogspot, use this publishing option to add your online forms.
