i want to filter the list

[Nikky]

you want to filter the map so that only values (list) that contain the items are in the result ?
or do you want to map over it filtering the lists ?

for the former: map.filterValues { it.any { searchQuery == it.propertyName}}
for the latter:

map.mapValues { (key, list) -> 
    list.filter { searchQuery == it.propertyName }
}

or similar

[oday]

filter the list inside the map for values that match a criteria, and then if one of the lists that belong to a key was empty after this previous filtering for criteria, that key must also be removed

[Nikky]

val filteredMap = map.mapValues { (key, list) -> 
    list.filter { searchQuery == it.propertyName }
}
.filterValues { it.isNotEmpty() }

maybe something like that ?
