Does the built in thank you page function have as much flexibility to include widgets and the like?

Now I've almost finished my form, I'd like to know some info about the thank you page please.

Basically I do want to be able to use some of the form fields, like name and email in read-only, but I would also like to have a predefined google map and directions for my address - "This is where we are..."

And also include another youtube video, some text, I'd like to move the facebook like widget from the bottom of my form to this thankyou page etc... and on the submission email, I want links to all of these things as well as a copy of the completed data from the main form

Does the built in thank you page function have as much flexibility to include widgets and the like? I can see it can have pictures, text and field data, but it just looks like an HTML text editor window.

Or would I need to create a new form and use the 'redirect to external link' feature if I wanted to do create these extra components (above) on my than you page?

In the custom thank you page template, the added fields is not similar in behavior when they fields are on the form. In the thank you page, the fields will show the data instead.

You can do this in the custom thank you page. Just add the fields and the data from those fields in the form will be displayed in the page as read-only data.

 but I would also like to have a predefined google map and directions for my address - "This is where we are..."

Since the google map widget will not show the actual map in the thank you page, you will have to manually embed the embed code of google map using the source code of the thank you page html code.

Example:

You can actually also create differnt custom thank you page base on condition logic. This is helpful if you want to show different thank you page base on the response on the form.

Hope this help. Let us know if you have further question.
