~~Title: Efl.Ui.Position_Manager.Grid~~
====== Efl.Ui.Position_Manager.Grid (class) ======

===== Description =====

%%Implementation of %%[[:develop:api:efl:ui:position_manager:entity|Efl.Ui.Position_Manager.Entity]]%% for two-dimensional grids.%%

%%Every item in the grid has the same size, which is the biggest minimum size of all items.%%
