         If you really need to override a Content Block, you can always fall back
         to traditional methods like :ref:`TCA Overrides <cb_extendTca>`.

+    ..  accordion-item:: How can I extend an existing Content Block?
+        :name: yaml
+        :header-level: 2
+
+        Same as before: This is not possible by default. Nevertheless, you can
+        always extend the TypoScript the old way and use e.g. partials from your
+        sitepackage or libraries from outside. But this way you are on your own.
+
+    ..  accordion-item:: Can I add PHP code to my content blocks?
+        :name: yaml
+        :header-level: 2
+
+        The Content Blocks API does support PHP files at all. If you want to add
+        some PHP logic to your content blocks, you have to use the old common
+        ways.
+
+    ..  accordion-item:: Can I use twig engine with Content Blocks?
+        :name: yaml
+        :header-level: 2
+
+        Not out of the box. As the main rendering engine for TYPO3 is fluid, you
+        have to do some custom work to get twig working with Content Blocks.
+
+    ..  accordion-item:: Can I use headless with Content Blocks?
+        :name: yaml
+        :header-level: 2
+
+        Content Blocks generating the TYPO3 core things under the hood (TCA,
+        TypoScript, tsConfig), so you have to prepare your headless setup like
+        you have to do with the core content elements.
+
+    ..  accordion-item:: Are the Content Blocks assets (JS and CSS) compressed by the the core?
+        :name: yaml
+        :header-level: 2
+
+        Content Blocks using the core asset collector, so the assets not get
+        merged together. Since they get registered only if the content block is
+        used on the page, each file is included separate.
+
+    ..  accordion-item:: Can I add Content Blocks assets (JS and CSS) to my build process?
+        :name: yaml
+        :header-level: 2
+
+        This is not a specific Content Blocks question. You can add your assets
+        to the build process like you do with any other assets. E.G. you can add
+        your Content Block CSS to your main CSS file, and remove the CSS
+        registration in the Content Block.
+
+    ..  accordion-item:: Can I add Content Blocks assets (JS and CSS) to my build process?
+        :name: yaml
+        :header-level: 2
+
+        This is not a specific Content Blocks question. You can add your assets
+        to the build process like you do with any other assets. E.G. you can add
+        your Content Block CSS to your main CSS file, and remove the CSS
+        registration in the Content Block.
+
+    ..  accordion-item:: Will there be a GUI (Graphical User Interface) for Content Blocks?
+        :name: yaml
+        :header-level: 2
+
+        Yes, the Content Types Team is working on a GUI for Content Blocks. The
+        first steps are already done, and we are looking forward to the first
+        beta phase in 2025.
