"All" is the default when no filters have been selected. It means, show me all results. You pick the filter you want by selecting it from the dropdown. Does this answer the question?
@gabrielliwerant Thanks!
I know that "All" is the default value or empty value but I want to choose one dropdown Item unconditionally
Do I have to use 'custom' to do this?
OR
Using filterList: ['Franky Miles'],' props, I could see item 'ALL'

Sorry, trying to get a handle on what you're looking for. Are you asking for a way to not show the "All" option? If so, you would have to go full custom to do this. Removing "All" will not be a supported option because this is the way to return to the default view in the interface. Without it, users will not be able to return to the default.

Thanks your answer!
