The pro Gallery has 3 item types Image/Video/Html. The code below shows a black area with error “TypeError: Cannot read property ‘fillColor’ of undefined”
{“type” : “text” ,
“alt” : “” ,
“title” : “Html Item” ,
“width” : 190 ,
“height” : 60 ,
“html” : “
I am a text block
” ,}
Please give me an example how to use the html item.
