Drop-In UI Overview


The Drop-in UI provides four levels of granularity:

  1. Pre-built components which attach to a parent element in browser DOM tree.
  • These components include region control and business tax number control.
  • They introduce their own DOM elements and handle events and logic.
  • It is possible to customise labels and text.
  1. HTML tag data-taxamo-* attributes, which enable you to attach Taxamo UI logic to existing DOM tree elements. This supports:
    • updating form field values
    • control visibility of form elements
    • two-way binding of fields to Taxamo API data
  2. JavaScript functions/handlers which can be attached to DOM elements programmatically.
  3. Direct calculateTax endpoint access from JavaScript layer

There are also events published using the standard JavaScript window.Event object.
