TYPO3 Core

In the parent task the icons for link wizard date picker and so on are put onto an button look and feel.

As this does not blog to irre but general tce forms the task got extracted

FYI, this may or may not be helpful here:

I had the need of having an actual button that submits a form on a couple occasions in EXT:solr and EXT:tika. Of course you could build that yourself in fluid, but that would mean duplicate code. So I created a view helper that does just that; render a form with a single button triggering a controller's action.

• icon
• ajax (when clicked replace icon with spinner, flash green when action was successful)

HTH, cheers
