![]() (I know it seems weird, but I do want to see everyone under the parent. So if I filter the “Employment Type” column for “contains Contract” I want to see everyone under Brittany Hanson and Francis Strickland. custom cell menu and header menu implemented with. For this example, I’m wanting to show a parent row with all of its children if a filter for a column passes. Collapsible group headers demo - A grid with collapsible grouped columns. What I’m wanting to do is very niche so I understand if the reasoning doesn’t make sense. The filterValueGetter returns the value of the grouped column - eg for Country, it will filter on Country.Hello have an example app below that I believe can use a custom filter component if possible (using textMatcher was just an idea in case it can also work somehow). To help demonstrate, the grid is configured to shade the rows different colors for the different group levels, so when you open a group, you can see the background change indicating that the group row is no longer displayed, instead the children are in it's place.įilter is achieved for each column by providing a filterValueGetter for the autoGroupColumnDef. The example below demonstrates hiding open parents using auto group columns. To allow closing the group again, the group column knows to display the parent group in the group column only (so you can click on the icon to close the group). 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. field is the only required property since its the column identifier. Notice that each group row has aggregated values which are explained in a documentation page of their own. The columns are defined with the columns prop which has the type GridColDef. ![]() To turn this feature on set groupHideOpenParents=true.īelow shows examples of this. This feature only makes sense when groups are in different columns. ![]() All rows that are not this group are blank. The column 'Country Group - No Renderer' configures the grid to put the 'Country' group data only into this column by setting showRowGroup'country'. This gives the impression to the user that the children takes the place of the parent row. The data is grouped by two columns: Type (one of 'Fiction' or 'Non-Fiction') and Country (a country name, eg Ireland or United Kingdom). 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. if two columns have the same field, or if you are using valueGetter instead of field) then it is useful to understand how column IDs are generated. If you are using the API and the column IDs are a little complex (e.g. Note how in the snippet above that the autoGroupColumnDef can be used to override any Column Property. Each column generated by the grid is given a unique Column ID, which is used in parts of the Grid API. To display each row group under a separate group column set groupDisplayType = 'multipleColumns' as shown below: this.
