Sensible defaults

The DX layer applies a small set of sensible defaults to keep your form definitions concise:

Default	Behavior
Auto-label	If you don’t provide label, the engine derives one from path (e.g. user.firstName → First Name).
Auto-placeholder	If you don’t provide placeholder, the engine uses path as a placeholder.
Auto-submit-button	If your formDef has no gui.actions.button/submitButton, the engine appends a default submit button.
Auto-stack	If your formDef has multiple top-level items and no top-level layout, the engine wraps them in a vertical flex.

Suppressing them

Each default can be turned off, either globally (via formConfig) or scoped (via a selector).

const formConfig = {
  suppressAutomaticSubmit: true,   // no auto submit button
  suppressAutomaticStack: true,    // no auto vertical wrap
};

const formSelectors = [
  // suppress auto-labels and auto-placeholders on every input
  gui.selectors.inputs({
    suppressAutomaticLabels: true,
    suppressAutomaticPlaceholders: true,
  }),

  // override that suppression for inputs tagged 'identity'
  gui.selectors.tag('identity').inputs({
    suppressAutomaticPlaceholders: false,
  }),
];
