Custom component in filter menu

The column.filter.ui is used to add custom filter components to a particular column. To implement custom filter ui, define the following functions:

  • create: Creates custom component.
  • write: Wire events for custom component.
  • read: Read the filter value from custom component.

In the following sample, dropdown is used as custom component in the duration column.

Enable different filter dialog for a column

You can use both Menu and Excel filter in a same TreeGrid. To do so, set the column.filter.type as Menu or Excel.

In the following sample menu filter is enabled by default and excel filter is enabled for the Task Name column using the column.filter.type.
