# Gallery

One viewer for a set of items, and a trigger for each. A trigger can be any element, usually a button holding the thumbnail. When the viewer closes, it flies back to the trigger of the item it shows and focus returns there.

#### React

`basic.tsx`

```tsx
import { itemLabel } from "@ogdakke/fluidbox";
import { Fluidbox } from "@ogdakke/fluidbox/react";
import { photos } from "./data";

export function Basic() {
  return (
    <Fluidbox.Root items={photos}>
      <div className="pattern-grid">
        {photos.map((photo) => (
          <Fluidbox.Trigger
            key={photo.src}
            item={photo}
            className="pattern-thumb"
          >
            <img src={photo.src} alt={itemLabel(photo)} />
          </Fluidbox.Trigger>
        ))}
      </div>
      {/* Without a Viewer, the viewer has these same three buttons. */}
      <Fluidbox.Viewer>
        <Fluidbox.Previous />
        <Fluidbox.Next />
        <Fluidbox.Close />
      </Fluidbox.Viewer>
    </Fluidbox.Root>
  );
}
```

#### Vue

`Basic.vue`

```vue
<script setup lang="ts">
import { itemLabel } from "@ogdakke/fluidbox";
import { Fluidbox } from "@ogdakke/fluidbox/vue";
import { photos } from "./data";
</script>

<template>
  <!-- Without a Viewer, the viewer has the default Previous, Next and Close. -->
  <Fluidbox.Root :items="photos">
    <div class="pattern-grid">
      <Fluidbox.Trigger
        v-for="photo in photos"
        :key="photo.id"
        :item="photo"
        class="pattern-thumb"
      >
        <img :src="photo.src" :alt="itemLabel(photo)" />
      </Fluidbox.Trigger>
    </div>
  </Fluidbox.Root>
</template>
```

#### Solid

`basic.tsx`

```tsx

  return (
    <Fluidbox.Root items={photos}>
      <div class="pattern-grid">
        <For each={photos}>
          {(photo) => (
            <Fluidbox.Trigger item={photo} class="pattern-thumb">
              <img src={photo.src} alt={itemLabel(photo)} />
            </Fluidbox.Trigger>
          )}
        </For>
      </div>
      {/* Without a Viewer, the viewer has these three by default. */}
      <Fluidbox.Viewer>
        <Fluidbox.Previous />
        <Fluidbox.Next />
        <Fluidbox.Close />
      </Fluidbox.Viewer>
    </Fluidbox.Root>
  );
}
```

#### Angular

`basic.ts`

```ts
import { Component } from "@angular/core";
import { itemLabel } from "@ogdakke/fluidbox";
import { FluidboxModule } from "@ogdakke/fluidbox/angular";
import { photos } from "./data";

@Component({
  selector: "pattern-basic",
  standalone: true,
  imports: [FluidboxModule],
  template: `
    <div fluidboxRoot [items]="photos" class="pattern-grid">
      @for (photo of photos; track photo.id) {
        <button [fluidboxTrigger]="photo" class="pattern-thumb">
          <img [src]="photo.src" [alt]="label(photo)" />
        </button>
      }
      <!-- Without a viewer template these three are the default; with one, you place them. -->
      <ng-template fluidboxViewer>
        <button fluidboxPrevious></button>
        <button fluidboxNext></button>
        <button fluidboxClose></button>
      </ng-template>
    </div>
  `,
})
export class Basic {
  readonly photos = photos;
  readonly label = itemLabel;
}
```

#### Elements

`basic.html`

```html
<fluidbox-gallery class="pattern-grid">
  <fluidbox-item item-id="photo-aurora">
    <button slot="trigger" type="button" class="pattern-thumb">
      <img src="/art/aurora.svg" alt="Aurora over the tundra" />
    </button>
    <template slot="content">
      <img src="/art/aurora.svg" alt="Aurora over the tundra" width="1100" height="1650" />
    </template>
  </fluidbox-item>
  <fluidbox-item item-id="photo-ridge">
    <button slot="trigger" type="button" class="pattern-thumb">
      <img src="/art/ridge.svg" alt="Night ridge" />
    </button>
    <template slot="content">
      <img src="/art/ridge.svg" alt="Night ridge" width="1200" height="1500" />
    </template>
  </fluidbox-item>
  <fluidbox-item item-id="photo-fjord">
    <button slot="trigger" type="button" class="pattern-thumb">
      <img src="/art/fjord.svg" alt="Fjord in the blue hour" />
    </button>
    <template slot="content">
      <img src="/art/fjord.svg" alt="Fjord in the blue hour" width="1200" height="1600" />
    </template>
  </fluidbox-item>
  <fluidbox-item item-id="photo-lagoon">
    <button slot="trigger" type="button" class="pattern-thumb">
      <img src="/art/lagoon.svg" alt="Lagoon after sunset" />
    </button>
    <template slot="content">
      <img src="/art/lagoon.svg" alt="Lagoon after sunset" width="1800" height="1200" />
    </template>
  </fluidbox-item>
</fluidbox-gallery>
```

#### JavaScript

`basic.ts`

```ts
import { createFluidbox, itemLabel } from "@ogdakke/fluidbox";
import { photos } from "./data";

export function mountBasic(root: HTMLElement) {
  // The viewer has Previous, Next and Close buttons unless you draw your own.
  const fluidbox = createFluidbox({ items: photos });

  const grid = document.createElement("div");
  grid.className = "pattern-grid";
  photos.forEach((photo, index) => {
    const button = document.createElement("button");
    button.type = "button";
    button.className = "pattern-thumb";
    button.append(Object.assign(new Image(), { src: photo.src, alt: itemLabel(photo) }));
    grid.append(button);
    fluidbox.bind(button, index);
  });
  root.append(grid);

  return () => {
    // Also unbinds the buttons.
    fluidbox.destroy();
    grid.remove();
  };
}
```

- The viewer has Previous, Next and Close buttons until you give it content of your own. Then the framework `Controls` part, `<fluidbox-controls>` or the `controls` option keeps them.
- In plain JavaScript, `fluidbox.bind(button, index)` makes each button a trigger, and `fluidbox.destroy()` unbinds them all.
- The trigger's image is where the flight starts and ends. Mark another element with `data-fluidbox-origin` to fly from it instead (see [Rich origins](https://fluidbox.dwe.workers.dev/docs/patterns/origins.md)).
