Breaking: #76108 - Replace ExtJS category tree with D3 and SVG¶
See Issue #76108
Backend ExtJS category tree has been replaced with one based on D3.js and SVG.
The js file
The expanded/collapsed state will not be saved to the backend user settings any more. It was not used in the core, as all category trees have setting 'expandAll' set to true. It also polluted backend user settings with tons of data without giving much usability gain.
Any JS code referencing ExtJS component
TYPO3.Components.Tree or its sub-components
TYPO3.Components.Tree.StandardTree) will no longer work.
All installations having extensions which modify the
or rely on the file being present.
Migration of the JS code to the new
SvgTree component is recommended.
