# `bitInput`

`bitInput` is an Angular directive to be used on `<input>`, `<select>`, and `<textarea>` tags in
order to provide standardized TailwindCss styling, error handling, and more. It is meant to be used
within a `<bit-form-field>` custom component.

## Basic Usage Example

```html
<bit-form-field>
  <bit-label>...</bit-label>
  <input bitInput formControlName="..." />
  <bit-hint>...</bit-hint>
</bit-form-field>
```

## Disabled `bitInput` and Error Handling

If you would like to be able to still show errors when an input is disabled for specific validation
scenarios, then set `[showErrorsWhenDisabled]="true"`

```html
<bit-form-field>
  <bit-label>...</bit-label>
  <input bitInput formControlName="..." [showErrorsWhenDisabled]="true" />
  <bit-hint>...</bit-hint>
</bit-form-field>
```

**NOTE:** Disabling a FormControl removes validation errors so you must manually set the errors
after disabling:

```ts
  get exampleFormCtrl(): FormControl {
    return this.form.controls.exampleFormControl as FormControl;
  }

...

this.exampleFormCtrl.setErrors({
  error: {
    message: this.i18nService.t("...", this.exampleFormCtrl.value),
  },
});
```
