error

Description​

defines whether error styling is applied to a combo

Type​

boolean

Default value​

false

Example​

<script>
    const dataset = [
        {id:1, name:"First option"},
        {id:2, name:"Second option"},
        {id:3, name:"Third option"}
    ]
</script>

<Combo options={dataset} value={1} error={true}/>

Details​

The property is useful during a form validation. If the property is set to true (or just specified without a value) and the input value fails validation, a combo gets error styling: the input's borders and the selected option's value become red.

To add a red error label for the control, use the error property of the Field control:

<script>
    import { Combo, Field } from "@wx/svelte-core";
</script>

<Field label="Error" error let:id>
    <Combo {id} error={true}/> <!-- equals to <Combo {id} error/> -->
</Field>
