Tabs

A state atom whose appearance (which tab is active) is a pure function of the state prop. Pass a state directly or drive it from the Remotion timeline via useCurrentState. The component reads no frame — only the state value you give it.

$ pnpm dlx shadcn@latest add @remocn/tabs

States

TabsState is:

type TabsState = string;

The state is the active tab's value — one of the strings in the items array. When the state changes, the active label brightens, the indicator (pill or underline) slides to that tab, and the matching panel crossfades in.

Snap usage

Pass state directly — the component snaps instantly to that visual. Useful for static previews or when you drive state from your own logic:

import { Tabs } from "@/components/remocn/tabs";
 
export const Scene = () => <Tabs state="Password" />;

To drive state from the timeline, use useCurrentState:

import { useCurrentState } from "@/lib/remocn-ui";
import { Tabs } from "@/components/remocn/tabs";
 
export const Scene = () => {
  const state = useCurrentState(
    [
      { at: 18, state: "Account" },
      { at: 58, state: "Password" },
      { at: 94, state: "Settings" },
    ],
    "Account",
  );
 
  return <Tabs state={state} />;
};

Each at is a Sequence-local authored frame. State persists between steps: Account at frame 18 keeps that tab active until Password fires at frame 58. See Concepts for the full useCurrentState API.

Smooth transitions

State changes via state snap with no cross-fade. For animated transitions, use useTabsTransition from the copied use-tabs-transition.ts file. It reads the frame, interpolates between state presets, and returns a resolved TabsStyle — pass it to the style prop:

import { Tabs } from "@/components/remocn/tabs";
import { useTabsTransition } from "@/components/remocn/use-tabs-transition";
 
export const Scene = () => {
  const style = useTabsTransition([
    { at: 18, state: "Account", duration: 16 },
    { at: 58, state: "Password", duration: 18 },
    { at: 94, state: "Settings", duration: 12 },
  ]);
  return <Tabs style={style} />;
};

The duration field on each step overrides the file's DEFAULT_DURATION for that specific transition. To globally tune timing and easing, edit use-tabs-transition.ts directly in your project — that file is yours (shadcn "own your code" philosophy).

style takes precedence over state when both are provided.
