Forms

Trek ships Trek::FormBuilder, an extension of ViewComponent::Form's builder, automatically used in admin views. On top of the standard helpers, it provides:

Helper	Renders
f.group	a label + input wrapper with errors
f.content_editor	the Tiptap rich text editor
f.image_field	an image uploader with thumbnail preview (Uppy + Shrine)
f.sound_field	an audio file uploader
f.switch_box	a toggle switch
f.link_select	a link picker (internal pages & external links)

Each helper renders the matching component from the Trek::Form namespace.

Standard helpers are styled too: a plain f.file_field inside an f.group gets its native ::file-selector-button styled like a narrow Trek::ButtonComponent (following the current data-accent-color), keeping the browser's built-in "file chosen" feedback with no JS — handy for one-off uploads like a spreadsheet import.
