Hello everyone,
I'm actually new to adf alfresco and i've been stuck with this problem for a while so i'll really need some help.
I want to modify one of the properties in adf-content-metadata-card , for example in order to modify a property of type "date" adf suggests for me a calendar, for my case if the user would like to modify a property i want adf to suggest for me a list of properties that are already saved in metadata (while for now adf only suggests for an input text) 
I tried to modify app.config.json by adding the following code
"content-metadata": {
"presets": { ... }, ...
},
but it didn't work, so my main question is it possible to add the list of the values in app.config.json or there is another method??
Any help would be appreciated, thank you ...
