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 OrderID column.

Enable different filter for a column

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

In the following sample menu filter is enabled by default and checkbox filter is enabled for the CustomerID column using the column.filter.type.
