Sveltekit megamenu

Need a sveltekit expert to help me with a resposive megamenu

Data will come from drupal 9 jsonapi and has 3x levels with name/description /image

I need mobile and desktop version


So parent term is depth_level=1, weight=0
/jsonapi/taxonomy_term/products?filter[depth_level]=1&sort=weight

child1 term is then a RELATIONSHIP to parent term
Child2 again to child1

/jsonapi/taxonomy_term/products?filter[depth_level]=2&sort=weight
