2 Blocks. Complete Control.

Gravity Forms1

A Gravity Forms wrapper block that brings your forms into the block editor with full theme styling support. Style every part of your form—labels, required indicators, input text, backgrounds, borders, radio buttons, and progress bars—using familiar block controls for color, typography, borders, shadow, and spacing. Drop in any Gravity Form and have it inherit your site’s design system automatically.

Responsive Grid

A flexible layout block with per-breakpoint controls for columns, alignment, and layout mode. Switch between grid and flex independently at each breakpoint, set custom column counts or widths, control horizontal alignment, and toggle equal heights—all without writing CSS. Live preview reflects the actual editor canvas width, so what you design is what you ship across mobile, tablet, and desktop.

  1. Requires an active Gravity Forms license and the Gravity Forms plugin installed. ↩︎
