First After Install Package
php artisan vendor:publish --tag=lfm_public
Then Inside vendor/file-filemanager/js/script.js
var myParam = location.search.split('multiple=')[1];//new
if(myParam == 'false'){ //new
multi_selection_enabled = multi_selection_enabled;//
}else{
multi_selection_enabled = !multi_selection_enabled;//here
}
Instead Of This Code
multi_selection_enabled = !multi_selection_enabled
Then Inside vendor/file-filemanager/js/stand-alone-button.js
window.open(route_prefix + '?type=' + type+'?&multiple=false',
'FileManager', 'width=900,height=600');
Instead Of This Code
window.open(route_prefix + '?type=' + type', 'FileManager', 'width=900,height=600');
Then Inside Vendor Laravel File Manager src/views/index.blade.php,you should uncomment this script line
<script src="{{ asset('vendor/laravel-filemanager/js/script.js') }}"></script>
It helped Me , You can try this .
