This add-on helps the developer to use Bootstrap components in a Vaadin project. It contains Java wrappers for: * Alerts * Badge * Breadcrumbs * Buttons * Button Group * Card * Collapse * NavBar * Listgroup * Form Layout * Responsive Grid Layout Some common classes for layout: * Color * Spacing * Display * Borders The add-on does not import any Bootstrap theme. You need to import a Bootstrap 4 theme in your Vaadin project to use the component. This will allow you to use the vanilla bootstrap theme or your own bootstrap theme. The demo contains a "translation" of the official bootstrap documentation. It's still incomplete. ## How to start You can find a documentation to import your theme here: https://github.com/jcgueriaud1/vaadin-bootstrap/blob/master/docs/IMPORT_CSS_JS.md And a minimal example with Spring Boot and Bootstrap 4.5 can be found here: https://github.com/jcgueriaud1/springboot-bootstrap-example Limitations: * The Vaadin components are not styled. I recommend to use Lumo and change the default variables (like primary color,...). It's a long work to make a Vaadin theme that will work for all bootstrap theme. * The default input components don't have any Java API. Use Vaadin input instead. * This add-on does not provide anything related to Bootstrap add-on. * You can't use the Bootstrap CSS classes inside shadow DOM. Recommendations: * This add-on is great if you already have an application that already use bootstrap and you want the same layout. * You can use this add-on for layout (menubar, top, footer, responsive grid layout) * I don't recommend to use this add-on if you're not familiar with bootstrap or if you start a brand new application without specific requirements for the theme.
