open a list in a checkbox usign a dropdow as filter

Filter a database list to display in checkboxes using a dropdown selection.

Overview

The issue occurs when trying to use a dropdown menu to filter database records for display in a checkbox list, as the checkbox field fails to populate with the filtered results.
Configure the form to properly link the dropdown filter to the checkbox field, ensuring the checkbox list dynamically updates to show only the relevant filtered items from the database.
