Data Den Header Filters

Header filters allows you to apply filtering for the data of a specific column. It is possible to apply multiple header filters at once.

Basic example

Use filter: true option to enable header filter in a column. By default all columns will use Text Filter.

                    {

                      headerName: "Price",
                      filter: true
                    },

                const gridEl = document.getElementById('grid');
                const dataDen = new DataDen(gridEl, options);

Built-in filters

Data Den comes with multiple built-in filter types:

Text Filter - a filter used to compare strings
Number Filter - a filter used to compare numbers
Date Filter - a filter used to compare JavaScript Date Objects
Select Filter - a filter that allows you to select the searched value from the list

By default all the columns use Text Filter. You can specify which filter should be used for a specific column in the column definition options. It is also possible to create a custom filter by defining a new filter renderer class.

The following example shows how to use built-in filters:

Column Car uses a Text Filter
Column Model uses a Select Filter
Column Year uses a Date Filter
Column Price uses a Number Filter
