CubeMX FATFS 'SD Card' tick box is greyed, why?

I'm trying to add FATFS to by CubeMX project targeting the STM32F767 processor. Even though I've enabled the SDMMC1 interface the only FATFS mode I can tick is 'User-defined'. Why is the 'SD Card' greyed.

Hello @Community member​ ,

It depends on your configuration, you should to active SD mode with SDMMC IP. 

There is a tooltip in CubeMx that can guide you as shown below:

Imen, thanks for that, I had it in MMC 4 bit mode and hadn't noticed the SD 4 bit mode. The screen shot you've posted is interesting because it shows tool tips. I hadn't noticed any tool tips and on investigation on my PC it's very reluctant to show them.
