# CheckBox ## `` - `post-text`, `pre-text`, `checked` (true, false, on, off, 1, 0), `default` (false, off, 0, true, on, 1), `error-message`, `warning-message`, `success-message` - actions: error, release, select, success, valid, warning - events: Release, Select ```xml ``` ## Guidance - Its text is `post-text` or `pre-text` (a click on it toggles); that text names the box. - Values: false/true, or on/off with `default="off"`, 1/0 with `default="0"` (`checked="on"` starts it checked); bound, it writes in the pair the node uses. - Select (checked) and Release (unchecked) fire for the user's toggle and for the `select` and `release` actions, when they change it; not for `set` or the bound document. A setting that applies at once is a `toggle`.
