0:00 All right, so let's get started on this actual form 0:03 back inside 0:04 of our create product model. So inside of our box here, we need to 0:08 render out a form. So let's go ahead and include 0:13 this HTML form, 0:15 and as we've done before, I'll give it a class name 0:18 and set width to full, max width x small. 0:23 And now I'll simply copy over an existing form we have. 0:27 So go to the sign up page and I'll copy out 0:31 our existing stack with our text field and button. 0:36 Copy this over and paste it in. 0:39 Simply provide the closing stack. 0:42 And now we just need to add our imports here. 0:44 So make sure we import all of these components from Material UI. 0:54 So in our other form so far, if you remember, we've been using 0:58 the useFormState hook from React DOM to manage 1:02 our form state.

Well, this is really easy to do with 1:25 Next.js because we can call server actions directly 1:28 ourselves in addition to using them in useFormState. 1:33 The first thing I wanna do is actually rename our 1:36 form error interface. So I actually want to rename this as 1:40 the form response. Now, this is more descriptive to me 1:44 because we have the error inside, and in the future 1:48 we might actually add additional properties to the form response 1:52 from the post call, like any data or extra properties, 1:56 and I want this to be more generic to just include the response. 2:00 So let's rename this as well to form response,
