Need Help in Slicer selection

Hi Amir851 

You may create a slicer table and then create a measure like below.Then use it in visual level filter.Attached sample file for your reference.

Measure = 
IF (
    HASONEVALUE ( Slicer[slicer] ),
    IF (
        SELECTEDVALUE ( Slicer[slicer] ) = "Under 1 Year",
        IF ( MAX ( Table1[Timeline] ) = "Under 1 Year", 1 ),
        IF (
            SELECTEDVALUE ( Slicer[slicer] ) = "Under 5 Years",
            IF ( MAX ( Table1[Timeline] ) IN { "Under 1 Year", "Under 5 Year" }, 1 ),
            IF (
                SELECTEDVALUE ( Slicer[slicer] ) = "Greater than 5 Years",
                IF ( MAX ( Table1[Timeline] ) = "Greater than 5 Year", 1 )
            )
        )
    )
)
