Advanced usage: custom form theme
A button is no more than anything containing collection-up, collection-down, collection-add
or collection-remove classes.
So you can customize buttons by creating a form theme for the form type that will be used inside the collection.
There is only 1 limit: if you're customizing the native collection theme, you should put collection elements in a div one level
deeper than the collection's root and no more. This is because the plugin uses $('#collection').find('> div'); to find collection's
elements. If you feel that the > div selector should be customizable in a plugin option, please open an issue on Github.
This demostration is made of the following files (click to see on GitHub in a new tab):
- Controller/AdvancedController.php
- Resources/views/Advanced/advanced-theme.html.twig
- Resources/views/Advanced/customFormTheme.html.twig
