plugin 'TagHelpers';
Most form helpers can automatically pick up previous input values and will show them as default. You can also use ``param'' in Mojolicious::Plugin::DefaultHelpers to set them manually and let necessary attributes always be generated automatically.
% param country => 'germany' unless param 'country'; <%= radio_button country => 'germany' %> Germany <%= radio_button country => 'france' %> France <%= radio_button country => 'uk' %> UK
For fields that failed validation with ``validation'' in Mojolicious::Plugin::DefaultHelpers the "field-with-error" class will be automatically added through ``tag_with_error'', to make styling with CSS easier.
<input class="field-with-error" name="age" type="text" value="250">
This is a core plugin, that means it is always enabled and its code a good example for learning how to build new plugins, you're welcome to fork it.
