[TYPO3-mvc] form.select add empty option

[Claus Due]

Hi Stefano,

The ->toArray() then array_unshift($options, $emptyOptionArray) is a fine solution, too :)

To explain the FED Select+Option ViewHelpers:

If you use <fed:form.select> and exclude the "options" argument, the FED ViewHelpers
will allow you to manually insert your <option> tags - and you can use <fed:form.option>
for those or simply render each <option> manually.

The main difference between the FED Select and Fluid's version is that "options" is not
a required attribute in the FED version - because you get additional <option> rendering
possibilities.

Cheers,

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 :)
