User tests: Successful: Unsuccessful:
This PR started to take care of the blue No values in the search module options. I added some other code improvements to it:
button and imagebutton parameter now use 0 and 1 as possible values instead of null (not set) and 1.button and imagebutton parameter now consistently default to 0 in XML and code.button_pos parameter now consistently defaults to left in XML and code.set_itemid parameter now uses the menuitem fieldtype. This allows users to select a menu item from the list instead of entering the number manually.switch statement into the if clause since it's only needed if a button is shown.This should change nothing for existing sites.
