Why does the merge function in Quick Stack only work with two or more rows in Webflow?

The Quick Stack merge function in Webflow only activates when multiple rows are present because merging affects content alignment and layout within a grid-like structure, which only exists when there’s more than one row.

1. Quick Stack Depends on a Grid Layout

• Quick Stack in Webflow is a shortcut for building responsive grid layouts.
• When you place child elements, Webflow automatically arranges them in rows and columns.
• Merge is only relevant when there’s a need to span content across multiple columns within the same row or across multiple rows.

2. Why Multiple Rows Are Required

• With only one row, there’s no structural difference between normal stacking and merging—there are no adjacent rows to span across.
• Merging in a grid modifies the row and/or column span of an element, which requires at least two rows or two columns to produce a visible effect.
• Webflow disables the Merge button unless the component context has enough rows/columns to make merging meaningfully possible.

3. How to Enable Merge in Quick Stack

• Add enough child elements to push the Quick Stack into creating multiple rows automatically based on its set max columns.
• Example: If your Quick Stack has max columns set to 3, adding a fourth item will trigger the creation of a second row—enabling the merge function.

4. When Merge Is Useful

• Use Merge to make a specific item occupy a larger visual space, such as spanning:
• Across all columns in a row (e.g., a header spanning full width)
• Vertically across multiple rows (e.g., a tall image or promo section)

Summary

The merge function in Webflow’s Quick Stack only works when there are at least two rows because merging affects how content spans across row/column boundaries. To activate it, you must have a structure where such spans are possible—typically by adding more items than the max columns setting allows, causing multiple rows.
