# Filtering

A filter is a powerful way of allowing users to interact with the data.

To get started, add a Filter web part:

![](/files/-MCsUUiOX6cgLuzq01a_)

Editing the Filter web part settings reveals just one option, the Property:

![](/files/-MCsUhwZufzvKvhbDqaw)

Select the field you want to provide a filter for.

If the field has fewer than 8 valid options, then Radio Buttons will be displayed on the page:

![](/files/-MCsUt0_t3Lww9odhETW)

Otherwise, a dropdown list will be shown:

![](/files/-MCsUxuV13mHb8xhjFiV)

You will notice that selecting an option will instantly re-render any charts on the page to apply that filter.

You also have the option of specifying whether you would like a dropdown, horizontal radio, or vertical radio buttons by setting the 'Field type':

![](/files/CNk9b5rowCgxNQ2g8AAV)
