CKEditor 5: wordbreak Plugin (TYPO3 Extension)

Compatibility

TYPO3 12.4.0 - 12.4.99

What does this extension do?

• This extension provides general support for the <wbr> HTML element in CKEditor 5 and TYPO3 v12
• Editors can insert the element by pressing a button at the current cursor position
• All <wbr> elements are highlighted in the editor (similar to the softhyphen)

<wbr>: The Line Break Opportunity element

• Allows a line break without adding a hyphen to the wrapped string
• Useful e.g. for long URLs or file paths, displayed on mobile websites or inside narrow parent elements

Line breaks are only applied by browsers if the word is too long for the surrounding element or viewport.
