![]() When the group is open, the group row is removed and in its place the child rows are displayed. When the group is closed, the group row shows the aggregated result. Notice that each group row has aggregated values which are explained in a documentation page of their own. To turn this feature on set groupHideOpenParents=true.īelow shows examples of this. This feature only makes sense when groups are in different columns. This gives the impression to the user that the children takes the place of the parent row. The count of each row group is removed by setting cellRendererParams.suppressCount = true.Ĭheckboxes are displayed beside each row group by setting cellRendererParams.checkbox = true.ĭepending on your preference, you may wish to hide parent rows when they are open. ![]() The min width of the group column is changed via minWidth = 220. The group column names are changed using the headerValueGetter to add 'Group Column' after each column name. The following example demonstrates some of the available autoGroupColumnDef configurations. The Auto Group Columns use the Group Cell Renderer to render group cells, and are configured via the cellRendererParams property. Note how in the snippet above that the autoGroupColumnDef can be used to override any Column Property. If you grab the child resize bar, only that one column will be resized.To display each row group under a separate group column set groupDisplayType = 'multipleColumns' as shown below: this. If you grab the group resize bar, it resizes each child in the group evenly distributing the new additional width. If you move columns so that columns in a group are no longer adjacent, then the group will again be broken and displayed as one or more groups in the grid. So if you have a group with 10 columns, 4 of which are inside the pinned area, two groups will be created, one with 4 (pinned) and one with 6 (not pinned). An incompatible set is one which will have no columns visible at some point (i.e. If a group has an 'incompatible' set of children, then the group opening / closing will not be activated. For example, in the code snippet above (and the example below), the 'Total' column is replaced with other columns when the group is opened. Having columns only show when closed is useful when you want to replace a column with others. ![]() If a group has any child with columnGroupShow set as open / closed, then the open / close icon will appear in the group header. null, undefined: The child is always shown.closed: The child is only shown when the group is closed.open: The child is only shown when the group is open.When a child has columnGroupShow set, it behaves in the following way: This is controlled by setting columnGroupShow on one or more of the children. If you provide attributes that are not applicable (eg you give a column a groupId) they will be ignored.Ī group can have children shown or hidden based on the open / closed state of the group. Most other attributes are not common across groups and columns (eg groupId is only used for groups).If it does not have a children attribute, it is treated as a Column. ![]()
