How to use Figma’s “SplitShape” plug-in
To divide an object evenly and repeatedly by specifying a numerical value, use the Split Shape plug-in.
Split Shape.
Draw an object (rectangle).
With the rectangle selected, search for the "Split shape" plug-in.
When the panel opens, enter the split settings.
Columns is the number of columns to split.
Rows is the number of rows to split.
Gutter is the distance between the objects to be split.
Margin is the left and right margins, but it is unlikely to be used much.
If "Split" is selected, the object is immediately split according to the settings you have made.
This is useful, for example, for creating carousel sliders, vertically and horizontally aligned card-type layouts, and grid layouts.
