Grid Builder
Audience: Editor.
The Grid Builder is a small bundled section pack plus a pair of column-split shortcuts. It's the fastest way to lay out a section without building columns by hand.
Bundled sections
Open the section picker → Grid Builder category. Seven sections ship out-of-box:
- 1 Column — single full-width column with a heading + paragraph stub
- 2 Columns — two equal columns
- 3 Columns — three equal columns
- 4 Columns — four equal columns
- 5 Columns — five equal columns
- Wide + Narrow (2/3, 1/3) — first column 66.6%, second auto-fills
- Narrow + Wide (1/3, 2/3) — mirror of the above
Each is a plain is-section with an is-container and the column structure. Drop one in and start editing — text and images are immediately editable.
Column split buttons
ContentBox's column popup ("…" icon when you select a column) gets two extra buttons:
- Horizontal split — adds a sibling column to the right of the active column. The new column inherits styling, so 1+1 split into 2+2 quickly.
- Vertical split — divides the active column vertically into two stacked nested rows. Useful when you want a column to contain its own mini-grid (image on top, text underneath, both inside the same outer column).
The buttons read builder.activeCol / .cell-active to find the target column, so they only fire when a column is actually selected.
When to use which
- Bundled section — when you're starting a new section from scratch and want a clean layout in one click.
- Horizontal split — when an existing 2-column section needs to become 3 without losing content.
- Vertical split — when one column needs to hold two stacked elements that should resize independently of the rest of the row.
