Hey @ozp
if you are looking for this feature for uvdesk open source then we are working on this as a separate module that provides you the ability to add the ticket form code to your website.

We already have the form builder app for UVdesk SaaS-based version, you may check this https://www.uvdesk.com/en/apps/form-builder-app/ & can go for SaaS based version as well.
