Nested Checkboxes are not working when checked ReactJS

I have a function which triggers children checkboxes once main checkbox is checked, the main checkboxes (Highest order) and all of the children checkboxes under them (2nd order) are shown on check and its working great, now I am trying to show the children of those children of the main checkboxes (3rd order).

Basically to show all three orders under each other on check, and add the 3rd order to my current code, so Options Group shows Options, and under Options is what i want to show, which are Option 1, Option 2, option 3 and so on..

The checkbox values are passed as props from Checkbox.js to Itemlist.js where the fetch/map happens.

As I was trying to achieve this, I have been able to show each of these 3rd order checkboxes but each one alone instead of showing them as nested checkboxes. I've tried to include it in the existing mapping function to show them all as nested checkboxes as mentioned but it couldn't work it only works if it was mapped alone instead of the current mapped path which is const selectedItem. while the mapping path of the targeted checkboxes (3rd level) are added in Itemlist.js as const selectedMod, I am not sure how can this be done should i map it twice at once or should i create another compoonent, testing any idea isnt achieving anything from what i want.

What I reached for so far to show the targeted checkboxes but individually: https://codesandbox.io/embed/o932z4yr6y?fontsize=14

Checkbox.js

      limit: 2,
      checked: false
    };
  }

  selectData(id, event) {
    let isSelected = event.currentTarget.checked;
    if (isSelected) {
      if (this.state.currentData < this.props.max) {
        this.setState({ currentData: this.state.currentData + 1 });
      } else {
        event.preventDefault();
        event.currentTarget.checked = false;
      }
    } else {
      if (this.state.currentData >= this.props.min) {
        this.setState({ currentData: this.state.currentData - 1 });

        event.preventDefault();
        event.currentTarget.checked = true;

export default Checkboxes;

Itemlist.js Where the mapping function happen

...

      const selectedItem =
        selectedChild.children && selectedChild.children.length
          ? selectedChild.children[this.state.itemSelected]
          : null;

...

  <div>
                {selectedItem &&
                  selectedItem.children &&
                  selectedItem.children.map((item, index) => (
                    <Checkboxes
                      key={index}
                      name={item.name || item.description}
                      myKey={index}
                      options={item.children}
                      childk={item.id}
                      max={item.max}
                      min={item.min}
                    />
                  ))}
              </div>
