I have build a new form connected to a sharepoint list using the responsive designer. The list itself should not be viewed by people submitting the form.
I have changed the submit button to link to a sharepoint page saying thank you for your submission. However, the "Close" button in the banner still links to the Sharepoint list.
How do either remove the option to close the form or redirect it when pressed?
Unfortunately there is nothing that can remove it within the new responsive designer. The only way to remove it would be to remove the element from the page or hide it within the CSS.
This is how you would do it within the Classic designer for Nintex forms, but that option is not currently present within the new responsive designer.
Hope this helps!
