If you want your database to be sorted by ACF field, add the code below to MapSVG > Menu > JS > databaseLoaded (replacing the existing code).
Change fieldName
to your own ACF field name.
function(){
this.database.getLoaded().sort((objA, objB) => objA.post.acf.fieldName > objB.post.acf.fieldName ? 1 : -1)
}
