create a vertical slicer of parameter slice

Hi absolut33,

Welcome to Microsoft Fabric Community Forum and Thank you for your question!

It looks like you're currently using a list-style slicer with checkboxes to display values from 1 to 20, but you’re aiming for a cleaner, more interactive vertical slider with a draggable point instead.
To achieve this in Power BI, you can modify your slicer to use a slider format. Select the slicer visual, go to the Visualizations pane, and change the slicer type to “Between” or “Less than or equal to” from the dropdown. This will transform it into a slider-based interface.If you prefer a vertical layout, open the Format pane, navigate to General -- Orientation, and switch it to Vertical.
Also, ensure your parameter column is numeric to enable this functionality. If you want only one value to be selectable at a time, you can go to the Format pane -- Selection controls, turn on "Single select," and turn off "Multi-select with CTRL." This will give you a clean, user-friendly slider experience. Feel free to reach out if you need help building a parameter table or linking this slider to specific measures.
