This option allows you to add a customizable parameter text box in a dashboard filter,
enabling users to enter or search for specific values during runtime.
When enabled, the Display a text box parameter option overrides all
predefined values included in the Specified values option on the
Values tab of the Settings modal window.
Instead of selecting from a list, you can enter a parameter value that you want to use at
runtime, or search for data that matches certain values. It creates a simple search box
filter.

Hover over the filter and click .
The Settings modal window appears.

a text box parameter option.
Click APPLY.
A parameter filter textbox appears as a filter.
Enter a value in the textbox.
In this example All-Bran is added.
The visual automatically gets updated and displays data related
only to All-Bran.
