Issue with Field Parameters

[Masthi]

Hi Team,

I have a urgent requirement. Kindly help me on the below issue.

Issue:

when I select individual column/select all from the field parameter (slicer), fields are adding to the table visual based on my selection (this is expected).
But when I deselect the "select all" from the field parameter (slicer), it is not removing all the fields from the table visual, it should remove all the fields from table [visual.It](https://visual.It) is the issue.

Hello @Masthi ,

Yes, this is how field parameter works, when you don't select anything it shows everything.

incase, you only want to show one column from it you could make the slicer to single select thus always one field will be selected.

It's the normal behaviour to show all the columns even when you deselect the Select all option. I'm afraid you will not be able to remove all the columns from the table. Atleast one need to stay there.

Hi @miTutorials Thanks a lot for your quick response.

How can you say that that is expected behaviour.
I believe that is a bug with field parameters.

When you say  "Atleast one need to stay there", the table is already having the default columns (Columns: Market and Region). Please find the below snips.

@Masthi , what he means at least one of the field parameters field should be there else if none was selected they will all be there.

it's always been like this and its not a bug.

@Idrissshatila @miTutorials  I have identified one workaround as below.
--I have created a Column Called None with all blank values of "". 

--Rather than deselecting "Select all", select "None", it will remove all the field parameter fields from the table visual. It is working as expected.
--Is there any way to handle the None column(hide it in visual level) from the visual level??

because users point of view it is not ok to show them in the visual level.

@Masthi ,and if the user selected something other than none then deselected his selection it will reshow all columns again.
