[TYPO3-mvc] form.select add empty option

[Claus Due]

Hi Stefan,

I have very recently submitted a patch for Fluid which will (if merged) allow you to exclude the "options" argument and manually add <optgroup> and <option> tags inside the <select> while still preserving the form's __hmac value. If you need it quickly you can find it in the extension "fed" [1] or you can wait for 1.4 / 4.6 which I hope will include the patch :)

Alternatively you might prefer this:

<f:form.select options="{f:if(condition: themes, then: themes, else: {mylabel: 'MyValue'})" />

Which, of course, only uses the placeholder if your {themes} variable does not contain options or is not defined/passed in the template :)

Cheers,
Claus Due

PS: the SelectViewHelper does add an empty option for valid output when no options are given, but unfortunately you cannot specify what the option should contain (both value and label will be empty strings).
