# DigiComp.FluidRenderFunctions

## Quickstart

This Package provides you with the possibility to register render functions, created from them, to use them dynamically else where.

Let me show you the idea:
```html
<f:form.select options="{books}" />
```
Assuming you know how the SelectViewHelper works, you know, you can provide an "optionLabelField"-argument to adivce the ViewHelper to use a property of your options.
But, what if you want to use a complete template, to display your books?
FluidRenderFunctions to the rescue:
```html
<rf:registerRenderFunction as="renderBook" subjectName="myBook">
    {myBook.name} from {myBook.author.name}
</rf:registerRenderFunction>
<f:form.select options="{books -> rf:applyRenderFunction(function: 'renderBook')}" />
```

To make your live easier, FluidRenderFunctions augments the original `SelectViewHelper` and the `TextfieldViewHelper` with an optional `renderFunction` argument. That way, you can even use the usual Textfield to display formatted Datetime objects. Neat!

## Configuration

If - for whatever reason - you do not want FluidRenderFunctions to augment the original ViewHelpers you can opt out by setting `DigiComp.FluidRenderFunctions.enableAspects.select` or `DigiComp.FluidRenderFunctions.enableAspects.textfield` to `false`.
