v.ValidationSummary(vs => vs.Enable(true));
})
.Items(items =>
{
items.Add()
.Field(f => f.MultiSelect)

Bug report
The Form TagHelper does not provide support for hidden fields, similar to the HtmlHelper.
Reproduction of the problem
The Form TagHelper does not allow similar built-in configuration:
.Items(i =>
{
i.Add()
.Field(f => f.UserID)
.Editor(editor => editor.Hidden());
})
Expected/desired behavior
The Form TagHelper should support hidden inputs.
Workaround
Similar result can be achieved by setting the editor-handler attribute, creating a hidden input and setting an empty label:
<form-items>
<form-item field="UserID" editor-handler="hiddenEditor" >
<item-label text=" " />
</form-item>
</form-items>
<script>
function hiddenEditor(container, options) {
$('<input type="hidden" data-bind="value: ' + options.field + '" name="' + options.field + '"/>')
.appendTo(container);
}
</script>

Bug report
Form TagHelper does not expose a ValidationSummary tag.
Current behavior
The Form TagHelper's exposes only a validation-summary attribute instead of a validation-summary tag which prevents adding options such as: Container, Enable, Template, and more.
In comparison to the HTML Helper .ValidationSummary() API configuration which allows the following:
.Validatable(v =>
{
v.ValidationSummary(validationSummary => {
validationSummary.Enable(true);
validationSummary.TemplateId("someTemplate");
validationSummary.Container("myContainer");
});
})
Expected/desired behavior
It would be a good idea to consider altering the current validation-summary attribute into a standalone tag helper. However, this will inevitably lead to a breaking change.
