I want to show category multiple-filter by hierarchical level

FILTER

Categories1(Open)
Sub Category1 (then again open)
sub sub category1

Categories2(Open)
Sub Category2(then again open)
sub sub category2

Categories3(Open)
Sub Category3

Please anybody can solve above problem. I am using this

instantsearch.widgets.refinementList({
container: ‘#categories’,
attribute: ‘hierarchical_categories.lvl2’,
//filters: ‘list_categories:Women’,
showMore: true,
searchable: true,
searchablePlaceholder: ‘Find a Category’,
limit: 5,
}),

but i want multilevel category Filter.
