# Group ## `` - `align`: right | left | center - `type`: row - `mode`: default | mutex | toggle - `value` (name of a child) - events: Disable, Enable, Select - methods: getMode ## Guidance ```xml ``` - Only direct children are in the set. `mutex`: one choice, kept - use it for radios too (only then a bound group follows its document). `toggle`: buttons with `selected`, the choice can be cleared. - Trigger on the group's Select; `{#v#size}` is the chosen radio's `value`, the pressed button's `value` (else its name, never its text) or the shown panel's name. `value=` takes the child's `name` only; the `set` action also takes a radio's `value`, and presses a button (by name or `value`) only in a `mutex` group. - Select also fires for programmatic changes (`set`, `value` at build, the bound document): gate user-only steps on a flag. - Panel children: only the one the value names is shown. Bind a radio group; a bound group of buttons is not supported (binding relabels the buttons and clicks stop setting the value). - Stacked radios (`type="row"`) need `style="line-height: 24px"` for the 24px target size.
