# Create advanced interactions using parameters

The HierarchyFilter extension allows you to set values of parameters based on selections made in the HierarchyFilter extension. This way you can create advanced interactivity between the HierarchyFilter and the Tableau sheets and visualizations in your dashboard.

When selecting an item in the tree, information about the selected item can be written into a parameter. This can be the name of the item, the level depth the item is in or what parent it as on a selected column. this can be seen in the video below with the selected Category, Sub-category, Manufacturer and Product Name.

To set this up, simply go to the "Interactions" page of the configuration.

On this page, select your parameters in the correct fields to write information to them. Keep in mind that the parameters need to be of type String. Except for the level parameter. The level parameter needs to be of type Integer. Make sure you only use a parameter for one option to prevent unexpected behavior.&#x20;

The "Reload hierarchy tree when selected parameter changes" checkbox shows all parameters in the datasheet as seen below. Each parameter that is selected here will cause the HierarchyFilter extension to reload when its value changes. this can be used to live update the data in the extension.
