I have created a hubspot landing page. I have also created a hubspot form. (I am using theFREE version). The form is for people to register to an event.
I currently have a “register here” button. When I try to link it to the form there is no “form” in the drop down. I see content, blog, file and external.
Free tier won’t be a limiting factor here - you should still be able to do this. First thing to note is it appears you are trying to embed a form with a button, it’s a little simpler than this.
1 - Make sure you’ve created an Embedded form. There are 3x options available when you create a form, it’s that first one.
3 - It will say “No form selected” by default, but you should see the left hand side of the screenshot where you’ll be able to select your form. If for any reason you don’t see that, clicking the module on the page should bring it up (and not the row it’s in, sometimes easy to misclick!)
