InputEmail
The input type Email creates an input field for emails.
Construction
Code
<kol-input-email _label="E-Mail-Adresse" _icons='{"right": "codicon codicon-mail"}'></kol-input-email>
Example
Events
For the handling of events or callbacks, see
| Event | trigger | Value |
|---|---|---|
click | Input field is clicked | - |
focus | Input field is focused | - |
blur | Input field loses focus | - |
input | Value is changed by entering | Current value of the input field |
change | Entry has been completed | Current value of the input field |
Usage
Use the InputEmail component on forms that require the entry of one or more email addresses.
By default, the component is designed to capture a single email address. Set the _multiple attribute to capture multiple email addresses. Separate each email address with a comma (,).
Best practices
- Make sure to set
idandnamecorrectly so that the data is sent when you submit the form.
Accessibility
There is no validation of the recorded email addresses within the component. To indicate failed validation, use the _msg and _touched attributes.

Tab | Focuses the input field. |
Character limit and character counter
With the three attributes _max-length, _max-length-behavior and _has-counter, the input length can be flexibly limited and at the same time provide visual feedback.
Attributes
| Attribute | Type | Default | Description |
|---|---|---|---|
_has-counter | boolean | false | Global switch for the character counter. Only if this attribute is set (= true) will a counter be output. |
_max-length | number | — | Maximum number of characters allowed. Effective only if _has-counter is active. |
_max-length-behavior | "hard" | "soft" | "hard" | Specifies how the limit is handled if _max-length is set:- hard: Additionally sets the native maxlength attribute and prevents further input.- soft: Allows further input; the counter shows remaining or exceeded characters. |
Output variants
| case | _has-counter | _max-length | _max-length-behavior | Visible text |
|---|---|---|---|---|
| 1 | (empty) or false | — | — | — (no counter) |
| 2 | true | (empty) | — | n character |
| 3 | true | 5 | (empty) or hard | n/5 characters |
| 4 | true | 5 | soft | 3 characters still available(or 3 characters too many) |
If
_max-length-behavior="soft"is used, the nativemaxlengthattribute is not set - so the input field is not hard-limited.
Accessibility
- The counter updates with a 500ms delay so that screen reader events are concentrated and do not interrupt typing.
- For screen readers, a hidden text that is only visible to assistive technologies is also displayed, such as: “You can enter up to 10 characters.”
Examples
<!-- Nur Zähler -->
<kol-input-email _label="E-Mail-Adresse" _has-counter></kol-input-email>
<!-- Harte Begrenzung auf 5 Zeichen -->
<kol-input-email _label="E-Mail-Adresse" _has-counter _max-length="5"></kol-input-email>
<!-- Weiche Begrenzung auf 5 Zeichen -->
<kol-input-email
_label="E-Mail-Adresse"
_has-counter
_max-length="5"
_max-length-behavior="soft">
</kol-input-email>
Summary
- Without
_has-counterthere is never a counter. - With
_has-counterand without_max-lengthonly the currently entered number of characters is displayed. - With
_has-counterand_max-length,_max-length-behaviordetermines whether the limit is implemented hard (hard) or softly (soft).
