# Button
Use buttons for actions in forms, dialogs, and more with support for style, block, icon, and state.
Buttons are interactive elements that can be triggered using a mouse, keyboard, or touch. They are
used to indicate actions that can be performed by a user such as submitting a form.
For pairings in the bottom left corner of a page or component, the `primary` call to action will go on the left side of a button group with the `secondary` call to action option on the left.
## Guidelines
Pairings in the top right corner of a page, should have the `primary` call to action on the right.
### Choosing the `<a>` or `<button>`
Groups of buttons should have 1rem of spacing between them.
## Choosing the `<a>` or `<button>`
Buttons can use either the `<a>` or `<button>` tags. Choose which based on the action the button takes:
Buttons can use either the `<a>` or `<button>` tags. Choose which based on the action the button
takes:
- If navigating to a new page, use `<a>`
- If taking an action on the current page use `<button>`
- If the button launches a dialog, use `<button>`
## Submit and async actions
### Groups
Both submit and async action buttons use a loading button state while an action is taken.
Groups of buttons should be seperated by a `0.5` rem gap. Usually acomplished by using the
`tw-gap-2` class in the button group container.
Groups within page content, dialog footers or forms should have the `primary` call to action placed
to left. Groups in headers and navigational areas should have the `primary` call to action on the
right.
## Accessibility
Please follow these guidelines to ensure that buttons are accessible to all users.
### Color contrast
All button styles are WCAG compliant when displayed on `background` and `background-alt` colors. To
use a button on a different background, double check that the color contrast is sufficient in both
the light and dark themes.
### Loading Buttons
Include an `aria-label` attribute that defaults to “loading” but can be configurable per
implementation. On click, the screen reader should announce the `aria-label`. Once the action is
compelted, use another messaging pattern to alert the user that the action is complete (example:
success toast).
### Submit and async actions
Both submit and async action buttons use a loading button state while an action is taken. If your
button is preforming a long running task in the background like a server API call, be sure to review
the [Async Actions Directive](?path=/story/component-library-async-actions-overview--page).

Tailwind traditionally has a very large color palette. Bitwarden has their own more limited color
palette instead.

- Easier to maintain and make adjustments.

# Forms
Examples and usage guidelines for form control styles, layout options, and custom components for
creating a wide variety of forms.
## Overview
Component Library forms should always be built using [Angular Reactive Forms][reactive]. Please read
[ADR-0001][adr-0001] for a background to this decision. In practice this means that forms should
always use the native `form` element and bind a `formGroup`.
Forms consists of one or multiple sections, and ends with one or multiple buttons.
### Form Field
A form field is the most common section in a form. It consists of a label, control and a optional
hint.
<Story id="component-library-form-field--default" />
<Source id="component-library-form-field--default" />
### Radio group
A radio group is a form field that consists of a main label and multiple radio groups. Each group
consists of a label and a radio input.

# Iconography
Avoid using icons to convey information unless paired with meaningful, clear text. If an icon must be used and text cannot be displayed visually along with the icon, use an `aria-label` to provide the text to screen readers, and a `title` attribute to provide the text visually through a tool tip. Note: this pattern should only be followed for very common iconography such as, a settings cog icon or an options menu icon.

## Overview
All tables should have a visible horizontal header and label for each column.
The table component provides a comprehensive way to display, sort and filter data. It consists of
two portions, a UI component called `bit-table` and the underlying data source `TableDataSource`.
This documentation will initially focus on the UI portion before covering the data source.
## UI Component
The UI component consists of a couple of elements.
- `bit-table`: The main component that creates a native table element and applies the table styling.
- `header`: A container for the table header.
- `body`: A container for the table body.
- `bitCell`: A cell within the table. Used for both headers and content.
### Guidelines
- Always include a row or column header with your table; this allows screen readers to better
contextualize the data
- Avoid spanning data across cells.
- Be sure to make repeating actions unique by associating them with the object they relate to.
Example: if there are multiple “Edit” buttons on a table, a screen reader should read “Edit,
Netflix” for an edit option for a Netflix item.
- Use [Virtual Scrolling](#virtual-scrolling) for large data sets.
### Example

The below code is the absolute minimum required to create a table. However we strongly advise you to
use the `dataSource` input to provide a data source for your table. This allows you to easily sort
data.

## Data Source
Bitwarden provides a data source for tables that can be used in place of a traditional data array.
The `TableDataSource` implements sorting and will in the future also support filtering. This allows
the `bitTable` component to focus on rendering while offloading the data management to the data
source.

### Sortable
### Sorting
We provide a simple component for displaying sortable column headers. The `bitSortable` component
wires up to the `TableDataSource` and will automatically sort the data when clicked and display
an indicator for which column is currently sorted. The dafault sorting can be specified by setting
the `default`.

### Filtering
The `TableDataSource` supports a rudimentary filtering capability most commonly used to implement a
search function. It works by converting each entry into a string of it's properties. The string is
then compared against the filter value using a simple `indexOf`check.
```ts
dataSource.filter = "search value";
```

## Accessibility
- Always incude a row or column header with your table; this allows screen readers to better contextualize the data
- Avoid spanning data across cells
