I am having trouble accessing the nested structure - Does anyone have any suggustion? Do I need another foreach loop?

<?php foreach($page->checkboxes()->agendas()->toStructure() as $agendas):?>
<li><label><input type="checkbox" value="<?= $agendas->tag() ?>" id="<?= $agendas->tag() ?>"/><?= $agendas->title() ?></label></li>
<?php endforeach ?>

content:
    label: Content
    icon: text
    fields: 
      checkboxes:
        type: structure
        label: Checkboxes
        fields:
          agendas:
            type: structure
            label: Agendas
            fields:
              title:
                type: text
                width: 1/4
              tag:
                type: text
                width: 1/4

Watching. Iā€™d never even thought of putting a structure within a structure. Brilliant.

Since agendas is also a structure field, you have to call toStructure() on it as well, whereas your first toStructure() call is not correct:

$checkboxes = $page->checkboxes()->toStructure();
foreach ( $checkboxes as $checkbox ) {
  $agendas = $checkbox->agendas()->toStructure();
  foreach ( $agendas as $agenda ) {
    echo $agenda->title();
    echo $agenda->tag();
  }
}
