Form handling is an important part of web development. to make handling form easy,
we have a global form that always be submitted with any event func. What you need to do
is just to give an input a name.

For example:

Use ~.Attr(web.VFieldName("Abc")...)~ to set the field name, make the name matches your data struct field name.
So that you can ~ctx.UnmarshalForm(&fv)~ to set the values to data object. value of input must be set manually to set the initial value of form field.

The fields which are bind with ~.Attr(web.VFieldName("Abc")...)~ are always submitted with every event func. A browser refresh, new page load will clear the form value.

~web.Scope(...).VSlot("{ plaidForm }")~ to nest a new form inside outside form, EventFunc inside will only post form values inside the scope.
