# tr foreach

This block is part of the [`state ui`](https://docs.rual.nl/block-types/state%20ui) group and was last modified in core [`v13.0.4`](https://docs.rual.nl/core-versions/130004).

Serves as a dynamic container, generating an unique `tr` for each element in the specified array.

- array required `array` This array is the source of data for generating the individual tr elements. • Hidden when other fields are filled

- state key required `v13.0.4` `value` This state key is the source of data for generating the individual div elements. • Hidden when other fields are filled

- class `uiclass` Assigns a CSS class to the element. • Hidden when unused

- style `uistyle` Applies inline CSS style to the element • Hidden when unused

- attributes `uiattributes` Adds custom attributes to the element. • Hidden when unused

- state `state` Returns the element to the frontend state.

A typical wiring for [tr foreach](https://docs.rual.nl/block-types/state%20ui/state_foreach_tr): [with values](https://docs.rual.nl/block-types/array/array_of_values) feeds the `array` pin; [value](https://docs.rual.nl/block-types/value/value_default) feeds the `state` pin; the function out pin wires to an [execute](https://docs.rual.nl/block-types/function%20execution/function_custom_execute_from_trigger) block.
