39 | Getting started
40 | ---
41 |
42 | This project provides an Expandable RecyclerView with group items that can be individually expanded to show its children in a two-dimensional scrolling grid.
43 |
44 |
45 | Usage
46 | ---
47 | [Expandable Grid Item]
48 | Each GridRowHolder object receives a data array from RecyclerView adapter to display in a grid row. Then it breaks up the layout of its row in rectangular cells of equal size. Each cell displays a piece of data and can be selected by user.
49 |
50 | Please check the implementation of simple example.
