JS控制

在包裝元素上切換collapsible-open，而不是使用複選框——當觸發器位於其他地方時很有用。

No hidden checkbox needed — state is managed by the collapsible-open class.

窺視變體

collapsible-peek 顯示漸層淡入淡出和疊加觸發器的剪輯預覽。 覆蓋 --peek-height 以控制折疊時可見的內容量。

Frutjam is a Tailwind CSS v4 component library built around a PostCSS plugin architecture. Every component is a set of @utility definitions that integrate natively with Tailwind's utility pipeline.

Theming is handled entirely through CSS custom properties. Swap themes by setting a data-theme attribute on any container, or override individual tokens inline.

Components ship with sensible defaults and are designed to compose cleanly.

帶有可折疊組的外部觸發器

將觸發器和可折疊物件包裝在 collapsible-group 中，以使標籤位於 .collapsible 之外 透過 is-collapsible-open 和 is-collapsible-close 回應其開啟/關閉狀態。

Section A
This content is toggled by the button above, which lives outside .collapsible but inside .collapsible-group.
