Pre-Selected Slicer – Auto Select Current Period & Dropdown Expansion Issue

[RuchiK]

I am trying to implement a pre-selected slicer for Periods in Power BI. My requirement is to automatically pre-select the current period from my Period table.

• My Periods are defined in 6-month ranges (e.g., Apr 2025, Oct 2025 , etc.).
• On 1st October 2025, the slicer should automatically switch from the April 2025 period to the October 2025 period.
• I am using the PeriodLabel column from my Period table in the slicer.

To achieve this, I tried using a custom “Pre-Selected Slicer” visual, but I am facing two issues:

1. The pre-selection logic for the current period is not working as expected.
2. The dropdown expansion behavior of the custom slicer is restricted inside the visual’s border. Unlike the default slicer in Power BI, it does not pop out fully. Because of this, long values are cut off and the user cannot properly see or scroll through the items (see screenshot attached).

My Questions:

1. Is there a way to adjust the visual settings of the Pre-Selected Slicer so the dropdown expands outside the border (like a normal slicer)?
2. If not, what are the best alternatives to achieve automatic pre-selection of the current period in Power BI while keeping a user-friendly slicer experience?

Also, I am attaching two one measures I have used for dynamic pre selections :

1. Selected Period Start =

VAR Sel = SELECTEDVALUE(Periods[PeriodStart], BLANK())

VAR D = TODAY()

VAR Y = YEAR(D)

VAR AprThis = DATE(Y,4,1)

VAR OctThis = DATE(Y,10,1)

VAR CurrentPeriod =

    IF(D >= OctThis, OctThis,

       IF(D >= AprThis, AprThis,

           DATE(Y-1,10,1)

       )

    )

RETURN

COALESCE(Sel, CurrentPeriod)

2.

In Selected Period =

VAR StartDate = [Selected Period Start]

VAR EndDate = EDATE(StartDate, 6)

RETURN

IF(

    MAX('Date'[Date]) >= StartDate && MAX('Date'[Date]) < EndDate,

    1,

    0)

Hi @RuchiK 

Thanks for reaching out to the Microsoft fabric community forum. 

I would also take a moment to thank  @lbendlin , for actively participating in the community forum and for the solutions you’ve been sharing in the community forum. Your contributions make a real difference. 

As suggested, you can try using the Filter Pane with relative filters. This way the current period will automatically adjust based on today’s date, without needing a custom slicer.

2. Use the Filter Pane instead. It has Relative filter options.
