I've added a Coloring Game Widget to my project but there is no way to add images or change colors. No plus or minus symbols.
Am I missing something? Thank you.
there is a display bug that prevents you from seeing plus/minus buttons but they're actually there, under the bottom left corner of the lists, just click that blank area. Sorry for the inconvenient, will fix this ASAP.
As for the Masked Image, this is developed using CSS filters, which are not supported on IE (our Quick Preview is based on IE in the Windows version of the software. Try a preview on Chrome or FireFox to see it working.
CSS filters are supported experimentally on Microsoft Edge browser, but you have to enable the feature manually: type "about:flags" in the address bar to access hidden properties.
