153Select is a collection of API methods, event handlers, event emitters and
154buttons (for the `Buttons` extension) for DataTables. It provides the following
155features, with an overview of how they are implemented:
156
157## Selection of rows, columns and cells. Whether an item is selected or not is
158 stored in:
159
160* rows: a `_select_selected` property which contains a boolean value of the
161 DataTables' `aoData` object for each row
162* columns: a `_select_selected` property which contains a boolean value of the
163 DataTables' `aoColumns` object for each column
164* cells: a `_selected_cells` property which contains an array of boolean values
165 of the `aoData` object for each row. The array is the same length as the
166 columns array, with each element of it representing a cell.
167
168This method of using boolean flags allows Select to operate when nodes have not
169been created for rows / cells (DataTables' defer rendering feature).
170
171## API methods
172
173A range of API methods are available for triggering selection and de-selection
174of rows. Methods are also available to configure the selection events that can
175be triggered by an end user (such as which items are to be selected). To a large
176extent, these of API methods *is* Select. It is basically a collection of helper
177functions that can be used to select items in a DataTable.
178
179Configuration of select is held in the object `_select` which is attached to the
180DataTables settings object on initialisation. Select being available on a table
181is not optional when Select is loaded, but its default is for selection only to
182be available via the API - so the end user wouldn't be able to select rows
183without additional configuration.
184
185The `_select` object contains the following properties:
186
187```
188{
189 items:string - Can be `rows`, `columns` or `cells`. Defines what item
190 will be selected if the user is allowed to activate row
191 selection using the mouse.
192 style:string - Can be `none`, `single`, `multi` or `os`. Defines the
193 interaction style when selecting items
194 blurable:boolean - If row selection can be cleared by clicking outside of
195 the table
196 toggleable:boolean - If row selection can be cancelled by repeated clicking
197 on the row
198 info:boolean - If the selection summary should be shown in the table
199 information elements
200}
201```
202
203In addition to the API methods, Select also extends the DataTables selector
204options for rows, columns and cells adding a `selected` option to the selector
205options object, allowing the developer to select only selected items or
206unselected items.
207
208## Mouse selection of items
209
210Clicking on items can be used to select items. This is done by a simple event
211handler that will select the items using the API methods.
