It depends how you want to save the data, I would normally write the logic like this:
1. get the id of the item you want to hide
2. push the item id to the hidden list (save it to the database)
3. before you load the notes data, you should filter out the id based on the id stored in the hidden list.
```
       let currNotesData = notesData.filter((notes) => {
         return hiddenList.includes(notes) })
```
1. Then, you can loop through the currNotesData and render the available component.
There are more ways to do this too

1. Create a table named "notes"
  
  1.1. The table should have a field named "isVisible". The data type of this field will be boolean and by default the value is set to true.
2. Create an API to change the visibility of the note, the method should be "PATCH".
3. Create an API to fetch the list of all the notes. In request parameters you have to add one parameter i.e.,isVisible and based on the value of the parameter the API will return the data.
  
  For example if you want to show all the hidden notes then your backend URL will look like http://localhost:3000/api/notes?isVisible=false
