Dynamic Select Fields
I have a recursive relationship in a table.
The table name is topics and each topic can have children and they can have their children etc.
I want the form fist show the select with options of topics that have parent_id = null.
Once selected I want another select to appear with the options that are children of selected.
And repeat this if the selected option has children until the selected item doesnt have any children.
