An extension to add CSS classes to Silverstripe forms to play nicer with Twitter Bootstrap
An extension to add CSS classes to Silverstripe forms to "play nicer" with Twitter Bootstrap, mostly by adding the
form-control bootstrap CSS classes to form elements (input, dropdown, submit etc).
This is designed to be a plug-and-play extension, without requiring you to change your existing forms on your website.
This includes all forms such as login forms, password reset forms, as well as any other form you have created.
FormField to try provide a transparent "manipulation" of the rendered form fields, adding some bootstrap CSS
to the rendered fields. It does not produce bootstrap-specific html for your forms.
FormField unfortunately only has a
$this->extend('onBeforeRender', $this); in
Field that allows manupulation of the
field itself, and not the parent field_holder. This allows only a very limited amount of flexibility, and prevents an
extension from changing the field_holder.
Form submit buttons get a
btn btn-primary class added, and any other buttons get a
btn btn-default class added.
Forms will still need some additional CSS styling (to set spacing) as the form's field_holders cannot be modified to the
limitations mentioned above.
It adds the
form-control CSS class to all front-end:
It renders CheckboxSetField & OptionsetField with different field templates (see templates/Forms).
It does not:
onBeforeRender()does not allow that)
You can install it via composer with
composer require axllent/silverstripe-bootstrap-forms
Simply install (and flush), ass the checkbox CSS to your styles and you're good to go.
