how to put mail sign-up + image in header?

Hey idaandersenlang,

Please refer to this post – http://kriesi.at/documentation/enfold/adding-a-widget-area-to-the-header/ and add widget area to your header.

You can enable debugging mode to see shortcodes you have created in pages using Advanced Layout Builder – http://kriesi.at/documentation/enfold/enable-advanced-layout-builder-debug/

Or, You can switch to Default Editor and click on Magic Wand to see full list of shortcodes http://i.imgur.com/n4KXkdm.jpg
then you can create any of them and copy/paste shortcode into any other content element or into text widget.

Best regards,
Yigit
