Install
npm install @dreamworld/dw-multi-value-field
Usage
By default value is Array of String. And to represent each value(String) in the Array, it renders dw-input
element.
For most of the practical use, you would like to render your custom form-element instead of dw-input
. To do so you need to override the method _formElementTemplate(itemIndex, itemValue, required)
, which should return the lit-html template for the corresponding form element.
For Example:
import { DwMultiValueField } from '../dw-multi-value-field.js';
export class DwMultiValueFieldDemo extends DwMultiValueField {
_formElementTemplate(itemIndex, itemValue, required){
return html `
<dw-date-input
.value="${itemValue}"
.index="${itemIndex}"
?required=${required}"
label="Date"
placeholder="Enter date here">
</dw-date-input>
`
}
}
