How to Filter Data in Slicer in Power BI: Advanced Techniques and Workaround
Power BI has become an indispensable tool for data analysis and business intelligence. However, even in such a powerful tool, users often come across limitations that can hamper their ability to fully leverage the features available. One such common challenge is the lack of direct support for visual-level filtering in slicers. This article explores an advanced workaround to filter data in a slicer by using a hidden "pre-Slicer", controlling interactions to affect only the designated slicer, and not all the visuals on the page.
Understanding the Challenge
Slicers in Power BI are used to filter data dynamically on reports, making it easier for users to find the information they need. However, the inability to apply visual-level filters directly to slicers can be a significant limitation. This means that if you want a slicer to only show specific data based on another filter, there isn't a straightforward way to do it using the basic settings. This limitation can lead to inefficient workarounds, confusion, and unnecessary complexity in reports.
Proposed Workaround: The Hidden Pre-Slicer Technique
The essence of this workaround involves using two slicers: a visible one that users interact with (the real Slicer) and another one hidden behind it (the pre-Slicer). The pre-Slicer is used to indirectly set the filters for the real Slicer, while the real Slicer interacts with the rest of the report.
Step 1: Setting Up the Pre-Slicer
First, create a slicer that will act as the filter for the real Slicer. This pre-Slicer should include the same field that you plan to use in the real Slicer. For this slicer, you don't need to worry about its visibility to the end-users, as it will be hidden.
Step 2: Configure the Real Slicer
Now, create the slicer that users will interact with. This Slicer needs to have a non-transparent background to effectively hide the pre-Slicer behind it. Configure the slicer as you would normally, according to your report's needs.
Step 3: Adjust Visual Interactions
This step is crucial. Go to the 'Format' tab, find 'Edit Interactions', and adjust the interactions between the pre-Slicer and the real Slicer. The goal is to ensure that the pre-Slicer only influences the filters of the real Slicer and not any other visuals on the page. This might require disabling some interactions to achieve the desired effect.

Step 4: Position the Pre-Slicer
Lastly, position the pre-Slicer behind the real Slicer. Thanks to the non-transparent background of the real Slicer, the pre-Slicer will remain out of the end user’s sight, serving its purpose silently.
Benefits and Limitations
Benefits:
- Allows for more dynamic and functional slicers that can adapt based on other filters.
- Enhances the user experience by simplifying the interface and focusing interactions.
Limitations:
- This workaround increases report complexity and may make maintenance more challenging.
- It's an indirect solution, making it less intuitive to set up and understand.
Hoping for Future Enhancements
While this workaround offers a temporary solution, many users hope for direct support for visual-level filters in slicers in future Power BI releases. You can share your thoughts and vote for such features on the Power BI Ideas forum:
