Lightbox and Galleries

Plan gallery browsing in Wappler: when to use inline grids, when to open large previews, and how to keep navigation usable as image counts grow.

Introduction

This tour helps you choose the right image-browsing pattern before you drop components onto the page. In Wappler, the biggest mistake is treating every media collection as the same job. A gallery grid, a masonry layout, and a lightbox overlay solve different user problems.

Choose the browsing mode first

Start with the user behavior you need. If the page itself should stay the main experience, keep images inline in a gallery or masonry layout. If the image deserves focused attention, open a lightbox or large preview only after the user asks for it.

Inline gallery

Good when thumbnails support the surrounding content.

Masonry layout

Useful when image heights vary and the page should feel editorial.

Lightbox

Best when the large asset deserves focused reading without leaving the page.

Inline first when images support the page

Overlay only when a larger preview helps

Keep navigation obvious in both modes

Plan the content shape

Before implementation, decide whether your gallery is static, page-driven, or data-driven. That decision changes where you prepare image metadata, captions, and thumbnail sizes.

Static showcase: curate images by hand

Content-driven gallery: repeat from a data source

Mixed editorial layout: combine text blocks and image groups

Implementation decisions

Once the browsing mode is clear, build the page structure so navigation stays obvious and performance stays predictable.

Pattern: masonry or card-based gallery

Use a repeating structure when the gallery lives in the page flow. Keep thumbnails consistent enough that the grid reads clearly, even if the heights vary. If the layout becomes visually noisy, reduce the number of competing image ratios before adding more effects.

Readable rhythm

Consistent spacing matters more than visual novelty.

Captions on purpose

Only show extra metadata when it helps scanning or selection.

Progressive reveal

Load more images in batches if the set is large.

Keep spacing and ratios intentional

Don’t overload every thumbnail with text

Use pagination or lazy loading for large sets

Open the larger image only from an intentional click. The page should still make sense without the overlay. In practice, that means the thumbnail, label, or caption should already tell the user why they would open the item.

Clear trigger

Users should know which image they are opening and why.

Context preserved

Closing the overlay returns them to the same place in the grid.

Keyboard-friendly

Next/previous and close actions should be easy to discover.

Use lightbox as a second layer, not the only view

Preserve gallery context when closing

Keep next/previous behavior obvious

Media-heavy pages rarely live in isolation. Assets Manager helps you reason about reusable image assets, while Pages and Front-End Components help you place those assets in the broader page workflow.
