HI
I have a a many_many relationship between

/Service.php
private static $many_many = array(
'Location' => 'Location',
	
);

/Location.php
private static $belongs_many_many = array(
'Service' => 'Service',
	
);

so there are lots of Locations with many Services on.

I have a drop down in a form which displays all Locations

new DropdownField( 'Locations ', 'Locations ' ,$locations->map('ID','Title')

what i would like is to display the Services underneath the dropdown in Checkboxes so people can select multiple services etc

So what they select a Location the relevant services display underneath.

Any Ideas would be greatly received

Many Thanks

Darren
