Can I call all the forms direct to the font end? without call the form by the picker? the scenario is: I want to create the form in the form tree and I need to reflect it direct without call it by the picker. that mean after save it will be direct reflect to the web page..

If you save a form that has been picked on a content page, then the content on the page will show the new version of the form automatically. So you only need to save the form to update the page.

@Sebastiaan I want to list multi form, not only one

You can put many form pickers on a document type, you can also add a block list / block grid editor on a document type and allow forms to be picked. Many ways to get multiple forms on a page.

@Sebastiaan it is Polls forms, so I want to create the polls and I want it auto reflect on the page, without pick the form it self

If you want the poll results to appear on the page in "live" updates then you'll need to use the Forms API to get the latest submitted data and display it on the page. I am afraid I can't help much more with this since I've never done it before but it should be possible.
