ModifyInlineElementControlsEvent
New in version 12.0
This event, together with ModifyInlineElementEnabledControlsEvent,
serves as a more powerful and flexible replacement
for the removed hook $GLOBALS
The PSR-14 event \TYPO3\
is called after the markup for all enabled controls has been generated. It
can be used to either change the markup of a control, to add a new control
or to completely remove a control.
Example
