Form Elements


Allows users to input and select data.


Input Fields



Main input fields across the platform



Default Select Boxes

We have two types of select boxes, the plain, non-javascript version which renders a fully styled outer box but comes with the default, native dropdown menu. An example of the default select can be seen here link.

It’s important to note that default select boxes must be surrounded by  .a-select-container div to appear correctly.

Javascript Select Boxes

We also have a Javascript version of the select which offers us more control when it comes to styles and customisations, in addition to giving us the ability to extend behaviour and logic. Previously we used Chosen and Select2 libraries for creating Javascript selects, however these are now deprecated and we now use React Select. A customised, multi-select example can be found here.

React Select Example


Expanders are useful for hiding optional subforms or additional content. A comment control is an example of an expander.



Toggle switches

Using the following component API call, the toggle should work automatically. For good accessibility, The label consists of the entire full-width area and the label text as well as the icons are clickable and should respond to keyboard events.

In some cases changing the state of the checkbox should submit the surrounding form (implemented using$(this).trigger('submit.rails') ). To enable immediate submit on change, add the class .js-immediate-submit to the .a-toggle-checkbox element.

To manipulate the value of checkboxes on the change event and toggle between 1 and 0 (which is the default for a single Rails checkbox), add the class .js-manipulate-value.

Grouping checkboxes

Use a .m-toggle-checkbox-group to contain multiple checkboxes, to display borders between each checkbox, but not on the last one.

Validation feedback

Add the error class to the form field & label in error to produce the FL Yellow outline. Use the novalidate attribute on the form element if the form has client-side validation, so our own styles takes precedence over browser defaults.

How to use write error messages

Error messages should be specific, helpful and provide clear instruction on how to fix the error.
