error

Description​

Optional. Defines whether error styling is applied to a combo

Usage​

error?: boolean;

Parameters​

  • true - error styling is applied
  • false - (default) error styling is not applied

Example​

<script>
  const dataset = [
    {id:1, label:"First option"},
    {id:2, label:"Second option"},
    {id:3, label:"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 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 "@svar-ui/svelte-core";
</script>

<Field label="Error message" error={true}>
  {#snippet children(id)}
    <Combo {id} error={true}/>
  {/snippet}
</Field>
