The filtering and paging function to fetch data about ecosystem is not working.（ url:[Ecosystem « P4 – Language Consortium](https://p4.org/ecosystem/) ） Filters’ checkboxes and buttons shows text like [facetwp facet=“product\_category”] rather than interactive html component. By the way,I want to know the most popular SDN controller which supports p4. ---

Hi, Yes I saw this a couple of days ago, I forgot to send an email. That is a good catch 😀, thanks for posting. To my knowledge, ONOS is probably your best choice, you can check the [following tutorial](https://github.com/opennetworkinglab/ngsdn-tutorial). Still, you can also use the python libraries available in the [P4 tutorials](https://github.com/p4lang/tutorials), and try to build your PoC controller. It is a long time I last heard about [OpenDaylight and P4](https://www.opendaylight.org/about/news/blogs/opendaylight-releases-oxygen-with-new-p4-and-container-support), they made a [plugin](https://wiki.opendaylight.org/display/ODL/P4+Plugin) a few years back but not sure if there is good support anymore. No idea about Faucet or Floodlight, but I think they might not support it. Cheers,
