There are quite a few threads like this, using HTML and/or CSS styles and JavaScript handlers to create tags. They work, but you lose much of the power of Bubble to organise and understand your app if you do it that way.
I’ve just created an incredibly simple plugin that makes any Repeating Group you choose flow from one row to the next, rather than being a fixed grid. It makes it simple to create HTML chips in pure Bubble, gives you complete design and interaction freedom, and doesn’t require any knowledge of HTML, JavaScript or CSS.
