The grid node lets you display elements in a grid.
Columns: Number of columns you want in your grid
Fill Row by Row: If turned on, elements will fill row by row and not column by column
Even Columns: All columns will have the same width
Even Rows: All rows will have the same height
Align: This will merge the edges of the elements together and remove the space between them
Enabled: This will disable elements in your interface to not be editable anymore
Active: Sets the layout as active
Split Layout: This will split your interface to display the properties aligned to the right side and the labels to the left. This matches the blender interface standard.
Decorate Layout: This will show keyframe indicators behind the properties. This input only works when Split Layout is enabled
Scale X/Y: This lets you scale the elements in your grid
Alignment: This lets you align the elements to a specific side of your grid
