I have tried with different approaches but can’t seem to get pinegrow to export a navigation block for me to add to my custom wp theme. I have made all kinds of blocks with no problem. They all have a bit of interaction and some custom code and still no problem with export. But when constructing nav/header/div for main navigation the block gets added to the code both in export folder and in local project but it doesn’t show up in site editor… What am I missing 
the block is even showing up in code inside the theme folder.
I use localwp for developing…
I did solve the problem, or I think I did anyhow.
I went checking some old videos in pinegrow tutorial section and stumbled upon the tutorial about building a onpage portfolio website. In one of the videos Matjaz mentioned that blocks with dynamic content needs to be in php version and not hybrid and I just got curious. So I changed just that block to php and re-saved it and exported it and low and behold. The block appeared as it should. So the solution was just that simple! Hope this can help others if it was the correct fix. It got solved for me anyway…
