HBS_CHILDREN

Returns the children of the current view model as a list. The view model must implement CompositeViewModel (e.g. ViewModelCollection). Returns null when the view model has no children.

Each child is processed using the sub-configuration of HBS_CHILDREN.

Frontend register

While iterating, HBS_CHILDREN writes two values to the frontend register that TypoScript conditions can read via register:

HBS_CHILDREN_COUNT – number of children
HBS_CHILDREN_CURRENT – index of the child being processed (unset after the loop)

Note

Since TYPO3 v14 the register is part of the frontend register stack on the global request object (frontend.register.stack request attribute) rather than the legacy $GLOBALS['TSFE']->register array. The extension handles both automatically.

Example

options = HBS_CHILDREN
options {
    label = HBS_LABEL

    checked = HBS_TAG
    checked.attribute = checked
}
