Solution 1:

It can be done using the aggregation pipeline in MongoDB.

Here in your case you have two nested arrays subMenu1 and subMenu2 first $unwind them and then use $match to achieve the result.

Mongo Shell Query

db.collection.aggregate([
    {$unwind:"$subMenu1"}, 
    {$unwind:"$subMenu1.subMenu2"},
    {$match:{"subMenu1.subMenu2.formName":"cavoucher"}}
 ])
