Is there a way to have only "Select all" and one of the options shown in the PowerBI slicer?

[monishd]

I have a slicer with two options: TRUE or FALSE. I want to show only options "Select All" and "FALSE." When false is selected, the data for FALSE is shown, and when "Select All" is selected, data for both true and false are shown in the table.

Hi, @monishd 

Since you didn't give specific data to test, I assumed a simple data set myself: 

You can then create a SlicerTable first via New Table like bhanu_gautam : 

SlicerTable = 
DATATABLE ( "Selection", STRING, { { "Select All" }, { "FALSE" } } )

Then create a simple Measure: 

FilterMeasure = 
IF (
    SELECTEDVALUE ( SlicerTable[Selection] ) = "FALSE",
    IF ( MAX ( 'Table1'[Result] ) = "FALSE", 1, 0 ),
    1
)

Finally drag the created Measure to the Filter panel and set the filter condition to 1. This is the final result: 

The pbix file for this example has been put at the end, I hope you find it helpful! 

I hope my suggestions give you good ideas, if you have any more questions, please clarify in a follow-up reply.

@monishd ,Create a Disconnected Table for the Slicer:
Go to the "Modeling" tab and select "New Table."
Create a table with the values you want in the slicer:
DAX
SlicerTable = DATATABLE(
"Selection", STRING,
{
{"Select All"},
{"FALSE"}
}
)
Create a Measure to Control the Data Display:
Create a new measure that will control the data display based on the slicer selection:

DisplayData =
VAR SelectedValue = SELECTEDVALUE(SlicerTable[Selection])
RETURN
IF(
SelectedValue = "Select All",
1,
IF(
SelectedValue = "FALSE" && [YourColumn] = FALSE,
1,
0
)
)

Apply the Measure to Your Visual:

Add the measure to the visual-level filters of your table.
Set the filter to show items where DisplayData is 1.
Add the Slicer to Your Report:

Add a slicer visual to your report and use the SlicerTable[Selection] column.
