Phoenix 1.7.0 brings a lot of new things when we run mix phx.gen my_app. These new and cool ways of doing things aren’t automatically brought to existing projects because they come from the generators. Of the many new things we could bring to an existing project, we focus on the new approach to form input components. Why? Because it’s both cool and useful! This post builds a custom multi-select checkbox group input for selecting which tags to associate with a database record in our Phoenix application. It’s surprisingly easy and elegant!
