TYPO3 Fluid - Exit a for loop

Is it somehow possible to break out of a for loop in fluid?

<f:for each="{subItem.image}" as="imageItem">
 <f:if condition="{selectedCategory} == {subItem.imagecategory}">
  Do Stuff
  Exit loop
 </f:if>
</f:for>

I need to loop trough a couple of images then render one if the category matches and exit the loop after that since I only want to render the first image with the matching category.

Maybe you can use a dataprocessor to give you an array with just the images in the category, and then you can just grab the first image with {imageItem.0}.

Have a look at TYPO3\CMS\Frontend\DataProcessing\FilesProcessor.

You can use Fluid variable view helper:

<f:variable name="imageRendered" value="0" />
<f:for each="{subItem.image}" as="imageItem">
 <f:if condition="{selectedCategory} == {subItem.imagecategory} && {imageRendered} == 0">
  Do Stuff
  Exit loop
  <f:variable name="imageRendered" value="1" />
 </f:if>
</f:for>
