# Variable Filter

Variable filters are used to quickly screen out the required data from the results obtained through variables. For example, using variables to obtain a respondent's score on a rating question, and then applying a variable filter to identify users who scored below 5 points, followed by displaying specific content.

After inserting variable tags in a rich text box and adding option reference settings in the option settings, clicking on the variable name will bring up a variable filter panel where you can make further settings for the referenced variable:

## Exclude from Response Data

This variable will not be recorded in the questionnaire response data results and is only available for variable tags inserted in rich text boxes.

## HTML Variable Placeholder Settings

You can set specific values for HTML placeholders, which is only available for HTML variable tags inserted in rich text.

## Media Dimensions

You can set the height and width of images inserted into text, which is only available for media variable tags inserted in rich text.

## Filter Conditions

Filter nodes that are conditionally extracted. Filter conditions are used for further filtering operations, requiring only the results of a variable that meets certain conditions to be referenced.

+ **Requirement**: Select the desired filtering method from the dropdown list.
+ **Meet the following conditions**: Select the required filtering operation from the dropdown list and enter the required value in the input box.

## Randomly Select Quantity

Randomly extract a specified number of option contents based on all previously required content.

## Shuffle Order

Shuffle the display order of the randomly extracted options.

Here is an example: A scoring question Q has 10 options, and the scored options of this question are referenced in a subsequent multiple-choice question.

Rules are as follows:

1. The option reference configuration rule is Q/scored options/option text;
2. Set filter conditions by selecting "**Score**" in the "**Requirement**" dropdown list, selecting "**Greater than or equal to**" in the "**Meet the following conditions**" column, and entering "**4**" in the input box, which means referencing all options with scores greater than 4 in the scoring question Q;
3. Select "**3**" for random extraction;

You can see that without any settings:

1. The multiple-choice question will apply to all 10 options;
2. After setting Rule 1, the multiple-choice question will reference 5 options with scores greater than or equal to 4;
3. After setting Rule 2, the multiple-choice question will reference 3 options drawn from the 5 options with scores greater than or equal to 4; if there are fewer than 3, all options will be displayed.
4. After setting Rule 3, the multiple-choice question will shuffle the display order of the 3 options drawn according to Rule 2;
