Blazor Data Form Example - Column Layout

This sample demonstrates the ColumnLayout functionality of the Blazor Data Form component. The ColumnLayout arranges form fields into multiple columns within the form container, improving readability and making efficient use of horizontal space to produce a visually balanced, user-friendly interface for desktop and tablet contexts.

Use the ColumnCount property to specify the number of columns for the overall form grid. ColumnCount determines how FormItems are distributed across the layout and influences wrapping behavior as the container width changes, allowing you to tune form density for different screen sizes and information complexity.

Apply the ColumnSpan property on individual FormItems to adjust their horizontal footprint across the defined columns. ColumnSpan enables combinations of compact inputs and wider controls (for example, multi-line editors or grouped controls), reduces vertical scrolling by consolidating related fields, and preserves alignment with adjacent items for clearer visual grouping.

Together, ColumnCount and ColumnSpan provide a flexible model for consistent alignment, predictable wrapping, and improved visual hierarchy. Adopt semantic field order and sensible span values to preserve keyboard navigation and validation message proximity, and test layouts across viewport sizes to ensure controls do not overlap and remain accessible.
