# wire.ui.validate

Validate multiple HTML elements on a page using the `wire.ui.validate` method.  This method will apply the validation configuration UI changes to the elements that fail validation.  It was return `true` if all the elements pass validation and `false` if at least one does not.

This method uses the [wire.validate](https://docs.wirebootstrap.com/wirebootstrap/reference/wire/wire.ui.validate) method for each element's validation.

## Parameters

| element | The root element for which descendant elements will be validated. |
| ------- | ----------------------------------------------------------------- |
| config  | The configuration for the validation.                             |

## Config Properties

Use the following properties on the second parameter `config` to configure the validation.

| Name     | Description                                                                                                                                                                                                                                                                                                        |
| -------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| css      | The CSS class to be added to each element that fails validation.                                                                                                                                                                                                                                                   |
| elements | The object containing the configuration to be applied to each element.  The configuration is the same as the one used in [wire.validate](https://docs.wirebootstrap.com/wirebootstrap/reference/wire/wire.ui.validate).  The name of each property should be the HTML element Id for each element to be validated. |

## Example

The following example validates three HTML elements.  All three are required.  `user-phone` needs to be a valid phone number and `user-email` needs to be a valid email address.  If any of these conditions fail, the `validate` method will return `false`.  The CSS class `invalid` will be added to any elements that fail validation.

```javascript
const valid = wire.ui.validate(document, {
    css: "invalid",
    elements: {
        'user-name': { required: true },
        'user-phone': { required: true, type: "phone" },
        'user-email': { required: true, type: "email" }
    }
});
```
