esp8266 wifi manager

I want to use the wifi manager to provide the option of connecting to the local wifi network, prompting for credentials, or alternatively to become a standalone access point. In both cases the ESP will run my web server program.

I have copied the example program (link below) and tried many of the commented commands, but so far the only thing I can do is prompt a web client to submit credentials and connect to a local network.

That example program starts in AP mode, if it had some option to skip the "configure wifi" function and simply continue in AP mode I think that would satisfy my needs.

I'm not looking for anything fancy, the simpler the better. I would be happy if upon failure to connect to the local wifi network it simply continued in AP mode.

Any suggestions are appreciated.

Thanks, Frank
