# Support

## Description

Hello,

I would like to ask if it's possible to fetch only certian fields with `lib.dynamicContent`

Something like ``

This is the relevant part inside my fluid template
```

XXX HEADER XXX

XXX SUBHEADER XXX

I've tried to modify `lib.dynamicContent` and add for instance `lib.dynamicContent.20.select.selectFields = header`

This unfortunately results in an error: `ERROR: Content Element with uid "5" and type "" has no rendering definition!`

Thanks in advance and best regards

Start by reading the lib.dynamicContent TypoScript configuration and the Fluid template snippet shown in the issue. Reproduce the selectFields change and inspect the rendering-definition error; done means establishing whether field-only fetching is supported and documenting the correct configuration or limitation.
