Hi everyone !

I have this code which will generate me a list of checkbox:

CheckboxSetField::create(
	'genres',
	'Liste des genres',
	array(
		1 => 'Pop',
		2 => 'Jazz',
		3 => 'Rnb',
		4 => 'Trap',
	)
);

I want set some attributes of these future checkbox, for exemple there onclick attribut.

How can I do ? Some one can help me please ?

I can't quite understand your question, but hopefully
http://api.silverstripe.org/3.1/class-CheckboxSetField.html
and
https://developer.mozilla.org/en-US/docs/Web/API/EventTarget/addEventListener
will help you.

Sorry if you're not understand me. it's a bit difficult to me to express myself in english. I'm not an anglophone.

Tanks for your answer.

What I want is custom the checkboxes in the CheckboxSetField class, by change some attributes before they will be printed in the template.

PS: Excuse my english ^^'

I understand English is not your language, don't worry :)

This is the CheckboxsetField template: https://github.com/silverstripe/silverstripe-framework/blob/3.1/templates/forms/CheckboxSetField.ss

You can copy it and put it in your templates folder (either in the theme or in your project [mysite/templates/forms/CheckboxSetFieldWithAttributes.ss])

Then you can edit it and use either
http://api.silverstripe.org/3.1/class-FormField.html#_setTemplate
or http://api.silverstripe.org/3.1/class-FormField.html#_setFieldHolderTemplate
on the field to make it use the new template (name it something different to CheckboxSetField.ss or it might always be used on CheckboxSetField)

Be sure to ?flush to make Silverstripe find the new template.
