#### **Category:**

\[Compulsory] This field is essential for rendering the visual. The user must provide category data here to ensure the filter functions correctly.

#### **Value:**

\[Optional] Users can include numerical data in this field to enhance the filter's usability and provide additional information.

#### Default Selection -&#x20;

\[Optional] Accepts a boolean (0/1) type column or measure where 1 is true and 0 is false. This field allows multiple columns, but you can keep only one of them as the default selection.

Use the below steps to add a custom default selection column.

* Create a new measure or calculated column using the provided DAX formula. Enter 1 for default selection values and 0 for others.

```dax
SampleMeasure = 
VAR _category = MIN('Categories'[Category])
VAR Result = 
    IF(
        _category = BLANK(), 
        BLANK(), 
        SWITCH(
            TRUE(),
            _category = "Category1", 1,   // 1 for selected category
            _category = "Category2", 1,   // 1 for selected category
            0                              // 0 for other categories
        )
    )
RETURN
    Result

```

* Drag this column into the default selection field.
* Go to the default selection option in advanced settings.
* Select “based on field” from the dropdown.
* Hit Apply.
* Result: This value will always stay selected by default.

{% hint style="success" %} <mark style="color:green;">IMPORTANT NOTES</mark>

* <mark style="color:green;">Ensure that the custom column or measure is of numeric type (0/1).</mark>
* <mark style="color:green;">Avoid using count and count distinct as aggregation types for columns, as they will display a count of all rows as 1.</mark>
  {% endhint %}

Read this section to learn how to add a [default selection](/powerviz/filter/advanced-settings-introduction/default-selection.md).

#### Image Data&#x20;

\[Optional] To use the image styling feature, you need to drag a Base64 URL image field into the Image Data Bucket.&#x20;

#### Tooltip

\[Optional] Users can provide data in either numerical or text format for the tooltip. This data will be displayed when users hover over items in the visual, offering additional context or information

#### Title

\[Optional] To enable a dynamic title in your visual, the user can create and provide a measure that determines the title based on the selected filters or data. This measure will dynamically update the title according to the current state of the visual.

```dax
DynamicTitle = 
VAR SelectedCategory = SELECTEDVALUE('Categories'[Category], "Default Title")
RETURN 
    "Current Selection: " & SelectedCategory

```
